The microprocessor controlled Aerosol Sampling Device ISAP 1050e is
designed for the determination of airborne homogeneously dispersed suspended matter (aerosols),
which are agglomerated fine dust particles of different composition, mainly emitted by
urban and industrial sources as machines, vehicles or combustions. Defined air volumes are
sucked through sampling heads (inlets), in which the aerosols are deposited accumulatively
on foils, filters or in polymer foams. With the subsequent laboratory works the mass concentration
of the aerosols and of their health-related components, such as heavy metals, their
compounds and complexed chlorohydrocarbons, can be determined by differential weighing
of the filters and by chemical / physical analysis of the sampled material.
The main field of application is the measuring of aerosol immission with aerodynamic diameters
smaller than 30 µm. The flow rate is 2.3 m³/h, thus, the ISAP 1050e is considered to be 'Low Volume Sampler' (LVS) or so-called 'Small Filter Device'.
The device type is reference / standard sampling device for the determination of the
mass concentration of total suspended particulates (TSP) acc. to VDI 2463 P. 1+7+8, of the
size-fractioned particulate matter (PM10.0/PM2.5) acc. to EN 12341 and its
element analysis as per EN 14902 and VDI 2267 P. 1 et seq. as well as for pentachlorophenol /
gammahexachlorocyclohexane (PCP / Lindane acc. to VDI 4301 P. 2). The device is also
conform with the European and German directives and standards relating to the limit values and
to the basis requirements of the equipment design for air quality monitoring according to
2008/50/EG, 39. BImSchV, ISO 7708, ISO 8756, EN 481 and TA Luft.
|
Since 1999 the ISAP 1050 series is listed as commercial reference sampler by the Chemical
Coordinating Centre (CCC) of the European Monitoring and Evaluation Program (EMEP), the
Norsk institutt for luftforskning (Norwegian Institute for Air Research NILU) and by the Global
Atmosphere Watch (GAW) of the World Meteorological Organization (WMO).
The type extension 'e' stands for an extended device version with the full range of accessory. For the different sampling, evaluation and
analysis methods there are diverse inlets, sampling tubes and compatible collection media sets available.
Beside the combined inlet for TSP and PCP / Lindane, the multi-stage inlets collect several PM fractions with each sampling. The collection media sets contain portioned adhesion grease, ring foils, round filters, carrier gauze and foam cylinders made of
different materials as aluminum, glass microfiber or quartz microfiber, polycarbonate (PC),
polyester, polyimide, polypropylene (PP), polytetrafluoroethylene (PTFE), polyurethane foam (PU) or polyvinylfluoride (PVF).
The optional ISAP 1050e high power pump module enables samplings with high flow resistance (backup) filters e.g. of PC or PTFE, which are most useful for pure optical evaluation methods
as Scanning Electron Microscopy (SEM) or for atomic spectroscopic trace element analysis of Al, Sb, As, Ba, Pb, Cd, Cr, Co, Fe, K, Ca, Cu,
Mg, Mn, Na, Ni, Se, Tl, V, Zn and Sn with Atomic Absorption Spectrometry (AAS), Gas Chromatography-Mass Spectrometry (GC-MS), Inductively Coupled Plasma
Mass Spectrometry (ICP-MS), Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), Proton-Induced X-ray Emission (PIXE) or Total
Reflection X-ray Fluorescence (TXRF).
With the Firmware and Comfort Control Software Versions 5.53 (sustainable) the automated operation supports the daily availability of the mass or/and element concentrations by a single automated longterm sampling project with runtimes up to six month using two or more Inlet&Pipe Sets for daily loss and contaminations-free quick-coupling exchanges for a timely laboratory works. Furthermore, these Versions also support wind depending samplings by default, executable by the optional combined Wind direction and Wind velocity Precision Sensor Package.
With the ISAP 1050e a large number of Usage period recalibration-free, professional Meteorological Stations and Precision Sensor Packages with auto-connect detection as per the ISAP hot plug & play principle enable the most accurate comparisons between the evaluated mass or element concentrations of different sampling sites or times, as well as diverse causal correlations with the environmental conditions. For samplings in areas with very low or very high environmental temperatures there are low, high and highest temperature packages available.
The ISAP 1050e is applicable for both outdoor and indoor measurements and recalibration-free for the regular total equipment lifetime.
The modular, compact and lightweight design following the ISAP plug & play, ISAP at a glance, ISAP 4 screws – 5 minutes and ISAP local upgrade principles enable an intuitive sampling project configuration, an easy equipment transportation, setup and operation as well as effortless maintenance and device firmware and control software upgrades at the operators' sites. This design feature for a prompt further usability leads to savings of environment-relevant resources and climate protection in raw material, production and transport as well as to less administrative effort with relevant overall economic advantage for the customers.

The type extension '31e' stands for an extended device version with filter changer and extensive accessory. The device allows a fully
automated time-scheduled sequential filter change for up to 31 days for a '24 h monitoring'. A filter magazine can contain up to
31 filter holders or 15 filter holders and 16 separators. The separators can be used to close the air space
above and below the loaded filters, so that the samples cannot evaporate or interact. As closed units, the filter magazines can be
changed most easy and contamination-free. The separate, optional thermostated filter housing section reduces losses of semi-volatile
compounds from the stored loaded filters on higher environmental temperatures.
For the different sampling, evaluation and analysis methods there are diverse pre-separator inlets for TSP or PM and compatible collection media sets available.
These sets contain portioned adhesion grease, round filters and carrier gauze made of glass microfiber or quartz microfiber, polypropylene (PP), polycarbonate (PC),

Fully Automated High Volume Aerosol Sampling Device ISAP 3000-31es (scientific) with universal filter changer
Design and Performance Level III. Quartar 2024 (DPLIIIQ2024) / Firmware and Comfort Control Software Versions 5.53 (sustainable)
Current core manufacturing process: single-unit assembling with optional application-oriented hard and software development as per contract or order confirmation.
|
|
The microprocessor controlled aerosol sampling device ISAP 3000-31es is designed
for the determination of airborne homogeneously dispersed suspended matter (aerosols), which are
agglomerated fine dust particles of different composition, mainly emitted by urban and industrial
sources as machines, vehicles or combustions. Defined air volumes are sucked through
a sampling head (inlet) and the aerosols are deposited accumulatively in the downstream filter changer.
With the subsequent laboratory works the mass concentration of the aerosols or
of their health-related components, such as heavy metals, can be determined by differential
weighing of the filters or by chemical / physical analysis of the sampled material.
The main field of application is the measuring of aerosol immission with aerodynamic diameters
smaller than 30 µm. The flow rate is 30.0 or 68.0 m³/h, thus, the ISAP 3000-31es is
considered to be a 'High Volume Sampler' (HVS).
The device is reference sampling device for the determination of the mass concentrations of
total suspended particulates (TSP) acc. to VDI 2463 P. 1 as well as of the size-fractioned particulate
matter (PM10.0/PM2.5) acc. to EN 12341 and its element analysis
as per EN 14902 and VDI 2267 P. 1 et seq. The device is also conform to the European and German directives and standards relating to the limit values and to the basis requirements of

Chemical Coordinating Centre (CCC) of the European Monitoring and Evaluation Program
(EMEP), the Norsk institutt for luftforskning (Norwegian Institute for Air Research NILU) and by
the Global Atmosphere Watch (GAW) of the World Meteorological Organization (WMO).
The type extension '31-es' stands for an extended device version with a special filter changer and a large range of accessories for scientific applications.
Beside an automated time-scheduled sequential filter change for up to 31 days with the 'Monitoring mode', also an event-induced filter change with direct
access to each filter holder carrier can be chosen. This 'Event mode' allows samplings to attain significant information regarding the sources of the aerosol,
the transport mechanisms in the air and the input mechanisms from the air to bordering media: so, depending on a number of relevant criteria, such as
Wind direction and Wind velocity, precipitation, relative humidity, or radioactivity or combinations of these parameters, priorly designated filters are moved
into the air flow.
The multiple use of the same filter group on identical event parameter configurations ensures a maximum work period of the filter magazine
and a minimization of blank value problems at analyzing. A filter magazine contains 31 carriers for standard filter holders or 15 carriers for (multi-stage)
impactor filter holders. As modular unit the filter magazine can be changed quick and easy. The separate, optional thermostated filter housing
reduces losses of volatile compounds from the stored loaded filters on higher environmental temperatures.
For the different sampling, evaluation and analysis methods there are diverse pre-separator inlets, single- and multi-stage impactor filter holders as
well as compatible collection media sets available. These sets contain portioned adhesion grease, round filters, slotted foils and carrier gauze made of different
materials as aluminum, glass or quartz microfiber, polypropylene (PP), polycarbonate (PC), polyester, polytetrafluoroethylene (PTFE) or polyvinylfluoride (PVF) for pure optical evaluation
methods as Scanning Electron Microscopy (SEM) or for atomic spectroscopic trace element analysis of Al, Sb, As, Ba, Pb, Cd, Cr, Co, Fe, K, Ca, Cu,
Mg, Mn, Na, Ni, Se, Tl, V, Zn and Sn with Atomic Absorption Spectrometry (AAS), Gas Chromatography-Mass Spectrometry (GC-MS), Inductively Coupled Plasma
Mass Spectrometry (ICP-MS), Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), Proton-Induced X-ray Emission (PIXE) or Total
Reflection X-ray Fluorescence (TXRF).
A large number of Usage period recalibration-free, professional Meteorological Stations and Precision Sensor Packages with auto-connect detection as per the ISAP hot plug & play principle enable the most accurate comparisons between the evaluated mass or element concentrations of different sampling sites or times, as well as diverse causal correlations with the environmental conditions. For samplings in areas with very low or very high environmental temperatures there are low, high and highest temperature packages available.
The device is applicable for outdoor measurements only and recalibration-free as well as and widely maintenance-free for the regular total equipment lifetime with an average number of two filter changes per day.
The modular design following the ISAP hot plug & play, ISAP at a glance, ISAP 4 screws – 5 minutes and ISAP local upgrade principles enable an intuitive sampling project configuration, an easy equipment transportation, setup and operation as well as effortless maintenance and device firmware and control software upgrades at the operators' sites. Same way, the ISAP 3000-31es can be adapted to new requirements by special hardware and software modules. This design feature for a prompt further usability leads to savings of environment-relevant resources and climate protection in raw material, production and transport as well as to less administrative effort with relevant overall economic advantage for the customers.

|
The microprocessor controlled aerosol sampling device ISAP 4000es is designed for the
determination of airborne homogeneously dispersed suspended matter (aerosols), which are
agglomerated fine dust particles of different composition, mainly emitted by urban and industrial
sources as machines, vehicles or combustions. Defined air volumes are sucked through
a sampling head (inlet) in which the aerosols are deposited accumulatively on large ring-foils, round-filters or
in polymer foams. With the subsequent laboratory works the mass concentration of the aerosols
and of their health-related components, such as heavy metals, complexed chlorohydrocarbons
or radioactive compounds can be determined by differential weighing of the filters
or by chemical / physical analysis of the sampled material as per EN 14902, ISO 11665-1 et
seq. and VDI 2267 P. 1 et seq.
The main field of application is the measuring of aerosol immission with aerodynamic diameters
smaller than 100 µm for the evaluation of mass or element concentrations, if these are very low in general or by meteorology-dependency, e.g. of wind direction and velocity, temperature, pressure, global or UV radiation or precipitation. The application-oriented flow rate is up to 1,000 m³/h and
thus, the ISAP 4000es is considered to be an 'Ultrahigh Volume Sampler' (UHVS). Due to the
high flow rate the device is predestinated for the determination of the mass concentrations of radioactively aerosol compounds also.
The device is conform to the European and German directives and standards relating to the
limit values and to the basis requirements of the equipment design for health-related air
quality monitoring acc. to 2008/50/EG, 39. BImSchV, ISO 7708, ISO 8756, EN 481 and TA Luft.

The type extension 'es' stands for an extended device version with a large range of Accessories and Options for scientific applications.
For the different sampling, evaluation and analysis methods there are diverse inlets and compatible
collection media sets available. Ultrahigh volume cascade impactor sampling inlets (UHVCI) allow the separate
determination of up to seven particle size fractions from PM10.0 down to PM0.156 by one sampling.
Up to over 150,000 high precision nozzles ensure the very sharp cut-offs.
The standard comfort collection media sets contain ring foils of glass microfiber or quartz microfiber. Special sets contain coated quartz microfiber back-up round filters and polyester protection gauze to sample the smallest fraction down to PM0.001. Other special sets contain ring foils of aluminum, polyimide, polycarbonate (PC), polypropylene (PP), polytetrafluoroethylene (PTFE) or polyvinylfluoride (PVF) for pure gravimetric determination of the aerosol mass concentrations by weighing or pure optical methods as Scanning Electron Microscopy (SEM) as well as for several established chemical/physical evaluation and analytic methods for quantitative trace element determination of e.g. Al, Sb, As, Ba, Pb, Cd, Cr, Co, Fe, K, Ca, Cu, Mg, Mn, Na, Ni, Se, Tl, V, Zn and Sn by atomic spectroscopic methods as Atomic Absorption Spectroscopy (AAS), Gas Chromatography-Mass Spectrometry (GC-MS), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), Proton-induced X-ray Emission (PIXE) or Total Reflection X-ray Fluorescence (TXRF).
With the Firmware and Comfort Control Software Versions 5.53 (sustainable) the automated operation supports the daily availability of the mass or/and element concentrations by a single automated longterm sampling project with runtimes up to six month using two or more ISAPUHVCI for daily loss and contaminations-free exchanges for a timely laboratory works.

The Cascade and Low-Pressure** Cascade Impactors ISAP CI and ISAP LPCI are designed for the determination of dispersed airborne particles (aerosols) in pipe flows or pipe outlets or in ambient air (emission or immission). Aerosols are agglomerated fine dust particles of different composition, mainly emitted by urban and industrial sources as machines, vehicles or combustions.
Defined air volumes are sucked through the impactor stages and the aerosols are deposited accumulatively size-selective on thin foil material and optionally on special treated backup filters. With the subsequent laboratory works the fractioned mass concentration of the aerosols and of their health-related components, such as heavy metals can be determined by differential weighing of the foils and backup filter and by chemical / physical analysis of the sampled material as per EN 14902 and VDI 2267 P. 1 et seq.
The ISAP(LP)CI are designed to sample coarse and fine dust particles within the analyzable aerodynamic mean diameters (AD50%) from 14.14 down to 0.09 µm. This range allows very compact and easy to handle inertial separation systems with good efficiency. Application-oriented special designs allow samplings with flow rates from 5 up to 60 l/min and cut-offs from PM0.065 up to PM20 with special pre-separator stages up to PM50. For the sampling of the total ultra-fine range the ISAP (LP)CI have an optional backup stage for 50 mm backup filters to collect the nano-particles down to PM0.001.
|
With the current ISAP (LP)CI a modular design with compact total geometry was developed, the loss-minimized flow geometry, the high collection capability due to large nozzle cycle diameters and large ring aerosol collection areas with one big center hole and the Reynolds numbers were further optimized, and a new sealing technology with ISAP auto-stripping principle, less stage part numbers and an integrated press function as well as microprocessor-controlled pump stations were developed. The achieved advantages are an energy-saving production process, a comfortable handling and automated, event-induced samplings, and correct and sharp cut-offs.
For the different sampling, evaluation and analysis methods there are diverse isokinetic inlets, special sampling probes, sampling
lances/flanges as well as compatible comfort collection media sets available. The collection media sets contain portions of grease, very thin ring
foils and optional round filters made of aluminum, polycarbonate (PC), polyester, polyimide, polypropylene (PP), polytetrafluoroethylene
(PTFE), polyvinylfluoride (PVF) as well as coated quartz fiber.
Beside the pure gravimetric determination of the aerosol mass concentrations by weighing or pure optical methods as Scanning
Electron Microscopy (SEM), there are several established chemical / physical evaluation and analytic methods for quantitative trace
element determination of e.g. Al, Sb, As, Ba, Pb, Cd, Cr, Co, Fe, K, Ca, Cu, Mg, Mn, Na, Ni, Se, Tl, V, Zn and Sn by atomic
spectroscopic methods as Atomic Absorption Spectrometry (AAS), Gas Chromatography-Mass Spectrometry (GC-MS), Inductively
Coupled Plasma Mass Spectrometry (ICP-MS), Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), Proton-Induced
X-ray Emission (PIXE) or Total Reflection X-ray Fluorescence (TXRF).
The High and Low Temperature Cascade Impactors ISAP HT-(LP)CI, ISAP LT-(LP)CI have special gaskets and allow samplings from media with temperatures of -50 up to +310 °C. Standard impactors can be upgraded with High or Low temperature gasket sets for the use with aforesaid media temperatures.
The automated operation is given by the use of the optional pump station ISAP (LP)CI-PSe. The type extension 'e' stands for an extended pump station with a microprocessor electronic unit, which allows the use of more accessory as well as automated samplings and a comfortable evaluation under inclusion of the environmental parameters at sampling site: An impactor temperature sensor and a large number of Usage period recalibration-free, professional Meteorological Stations and Precision Sensor Packages with auto-connect detection as per the ISAP hot plug & play principle enable the most accurate comparisons between the evaluated mass or element concentrations of different sampling sites or times, as well as diverse causal correlations with the environmental conditions.
With the Firmware and Comfort Control Software Versions 5.53 (sustainable) the automated operation supports the daily availability of the mass or/and element concentrations by a single automated longterm sampling project with runtimes up to six month using two or more ISAP (LP)CI for daily loss and contaminations-free quick-coupling exchanges for a timely laboratory works. Furthermore, these Versions also support wind depending samplings by default, executable by the optional combined Wind direction and Wind velocity Precision Sensor Package.
For samplings in areas with very low or very high environmental temperatures there are low, high and highest temperature packages for the pump station available.
The homogeneous and closed cover of the ISAP (LP)CI ensures a good fit and heat transfer on operations with a heating or cooling jacket.
The device is applicable for both outdoor and indoor measurements and recalibration-free for the regular total equipment lifetime and widely maintenance-free.
With the ISAP (LP)CI modular systems, within certain limits the cut-offs can be changed by modular replacement. This design feature for the further system usability after changed requirements leads to savings of environmental resources and to climate protection in raw material, production and transport as well as to less administrative effort with a relevant overall economic advantage for the customers.
** A low-pressure operation is simplified given for all stages with an exit pressure of about 50 percent or lower than the current environmental pressure at the impactor inlet stage.

Mobile Wind Solar Hybrid Energy Supply Systems ISAP WSH
Current core manufacturing process: single-unit assembling with optional application-oriented hard and software development as per contract or order confirmation.
The mobile wind solar hybrid energy supply systems ISAP WSH allow the operation of our
power consumption reduced low-volume aerosol sampling devices ISAP 1050eWSH and
ISAP 1050-31eWSH on sampling sites without any mains supply and also if a diesel
generator shall not be used.
|
The self-sufficient energy supply systems consist of a wind generator, two photovoltaic module groups and one
accumulator station. The system performance is adjusted in the planning through the choice of the wind generator
and the variation of the amount of photovoltaic modules to the typical regional wind and insolation conditions of
the intended measuring sites.
If additional energy should be required due to poor environment conditions on site, two additional photovoltaic
modules can be mounted on the spare places of the module group carrier frames.
With the interval function "time spans" our low-volume samplers can also provide results in light wind and low sunshine periods
by operation alternating, i.e. with sampling intermissions. The progress of wind strength and insolation can be gathered by
the optional meteorological sensors.
In order to be able to transport the systems easy and cost-efficient to different measuring sites, the components are modular,
i.e. as far as reasonably dismountable.

Application-oriented Special Design Aerosol Sampling Systems
Current core manufacturing process: single-unit assembling with application-oriented hard and software development as per contract or order confirmation.
Besides our standard devices we also deliver customer-specific samplers and sampler components, e.g. inlets, pump units and flow rate controller.
|
Example: application-oriented ISAP Special Devices for aerosol samplings in polar regions
|
In polar regions the devices are exposed to extreme low temperatures down to -65 °C, snow storms and
high altitudes up to 3000 m above sea level in the Antarctic.
This requires special features of devices and accessory against freezing and condensation - range from auxiliary heatings
over insulations up to special lowest temperature electronic elements and feed lines.
The special inlets must be protected against snow entry which has to be effective on horizontal strong winds and against
giant snow drifts.
Quotation order Inlet Design
Due to the very high effort in logistic for device applications in polar regions, subsequent improvements are excluded
- there is only one try.
We are glad that our intensive planning was successful and that the devices still work without relevant problems.

Example: application-oriented ISAP Sampler Units and wind-driven Control Units for aerosol samplings
on research vessels
For aerosol sampling on research vessels it is important to avoid the suck in of the exhaust fumes of the vessel.
The control units automatically switch off the sampling if the wind blows from the vessel chimney towards the
sampling device and also if the wind velocity is lower than a preallocated minimum threshold value to avoid
a contamination through undefined movement.
The initialization of the control unit is easily done by a PC communication surface:
Here, the sampling parameters as forbidden wind sector and the minimum threshold value of the
wind velocity as well as the delay time for the automatic restart can be altered.
To enable a complete and comfortable evaluation of the sampling, the wind parameters, the
compass course of the vessel and the device operation times are recorded and edited for an
export for spreadsheet evaluations.
The very special conditions on a research vessel are the high salt concentrations in air and sea spray,
the abrupt movements of the ship and massive flushes of seawater over the working deck.
|
This requires special features of devices and accessory against corrosion, damages due to movements
and the entry of sea water - range from housings made of special high- alloyed steel, over shock-absorbing
holders for pumps and electronics to sea water-resistant connectors and feed lines.
