Accessory for Aerosol Sampling

For our sampler devices and for foreign devices we design standard and special accessory. We design the special accessory on suggestion and in corporation with our customers.   Examples: Standard sampling head for TSP meeting VDI 2463 Bl. 8 and impactor sampling heads, impactors, single and multi-stage impactors (PM10, PM2.5, PM1.0) meeting EN 12341 / EN 14907 / EN 481/ ISO 7708 for High-Volume, Medium-Volume and Low-Volume Sampler (Small Filter Devices) with optionally heating for standard flow rates or special design for application oriented flow rates (0.5 - 230 m³/h) / cut-offs (0.008 - 30 µm)  Quotaton order Inlet design Sampling heads for gas and dust detection (e.g. PCP = pentachlorophenol, Gamma-HCH = hexachlorocyclohexane) meeting VDI 4301 Bl. 2 (high-grade steel / anodized aluminum) Sampling pipes: straight or curved with quick coupling (high-grade steel / anodized aluminum) Meteorological sensors: temperature, pressure, wind, humidity, precipitation, radioactivity et al. Teleprocessing packages: modem, ISDN Application-oriented special accessory and special constructions on demand Pumps, frequency converter Action controller electronic Volumetric flowmeter Device controller and data recording systems Quick couplings, filter and housings

Low-pressure Cascade Impactors by Prof. Dr. Berner and Vacuum Pump Stations

Cascade Impactors by Prof. Dr. Berner are designed for a particle size related sampling of ambient and industrial aerosols. Weight or mass size distributions and sizedistributions of elements and compounds are obtained according to the type of evaluation. The special characteristics are a very wide measuring range (0,008 up to 20 µm) in applying low pressures, so the entire size distribution of atmosphericand industrial aerosols are recorded by one apparatus. Foils of any material can be used for particle collection. Measuring range from 0,008 µm up to 20 µm Flow rates according to the requirements (standard: 25 l / 30 l / 80 liters per minute) Temperature range from -30 °C up to +120 °C (optionally from -50 °C up to +180 °C) Low-pressure Pump station for using aluminum or tedlar foils Accessory: mounting frame Extras: sampling probes, nozzle sets und sampling lances/flanges manufactured from high-grade acid-proof steel

Application-oriented special Devices and Sampler Components

Different Sampler Units for Aerosol Sampling on Research Vessels Besides our standard devices we also deliver customer-specific sampler and sampler components, e.g. inlets, pump units and flow rate controller. As separately service we calculate and draw a PM single- or multistage inlet for the extension of your existing systems:  Quotaton order Inlet design

Control units for an event-driven sampling

Wind-driven Control Unit for Aerosol Sampling 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 unit automatically switches off the sampling if the wind blows from the vessel chimney towards the sampling device or if the wind velocity is lower then a preallocated minimum sense, and so a contamination through a indefined wind direction is possible. The initialisation of the control unit is to do with a PC: Here, the device parameters "forbidden wind sector", the minimum sense of the wind velocity and the delay time for the automatic restart are altered. To enable a complete evaluation of the sampling by table calculation programs, all device and event parameters (wind, compass course etc.) are recorded in high resolution.

Wind-driven Control Unit for the Analysis of the ambient Air The control unit allows the analysis of the ambient air in a major wind sector. It is possibel to switch up to 4 analytical devices in a "analysis modus" or in a "zero air modus". The "analysis modus" - detecting the ambient air - is active when the wind direction is in the pre-allocated "analysis sector" and if the wind velocity is higher then a preallocated minimum sense. In all other cases the "zero air modus" is active: the analytical devices receiving clean bottle gas.

Pump Control Unit of a mobile Station for Measurement of Mass Concentration in ambient Air The control unit switches 3 Low-Volume sampler pumps and 2 High-Volume sampler pumps. The control unit is composed of a command and message unit and a switching unit. The attendance with the command and message unit is in the workroom inside of the station: for every pump existing the status signals START, STOP, ERROR, 2 meter panels and one temperature display. The volume recording of the High-Volume-Samplings is realized by pulse emitter devices and data storages. The switching unit with power and motor protection switches are mounted in the pump room that is inspectable from outside.
