- The MAS-100 Atmos® microbial compressed gas sampler
- The instrument is designed to collect microorganisms in compressed gases by gentle but direct impaction onto agar.
- Gas types Default: Compressed air, Nitrogen (N2), carbon dioxide (CO2), Argon (Ar)
- All connections are safe and decompression is controlled by the instrument. The additional safety features of the lid prevent accidental opening while the instrument is under pressure
- Minimize handling errors Automatic detection of pressure and a mass flow sensor ensure secure, accurate sampling of compressed gases.
• Automated flow rate regulation
• Compensation for pre-defined gas types (compressed air, N2, Ar, CO2) ensures the right amount of gas is sampled
• Automated decompression
- The software functions fulfill all requirements for data integrity according to 21 CFR Part 11.
- The impaction speed at a default flow rate of 100 LPM is identical to all other MAS-100® air samplers and provides a nominal d50 of 1.1 μm.
- Gas types Default: Compressed air, Nitrogen (N2), carbon dioxide (CO2), Argon (Ar)
- Gas flow rates:
Default: 100 L/min
Optional: 50 L/min
Optional: Automatic fallback from 100 to 50 L/min"
- Sampling volume: Configurable between 50 up to 3000 normal liter (NL)
- Standard conditions for normal liter: 20°C, 1013.25mbar(a), 0% relative humidity. Under these conditions, the air density is 1.2041 kg/m3

- Gas pressure range (bar absolute):
- The dynamic input pressure range (line pressure during sampling) is 1.2 bar.a to 7 bar.a (17.4 psi to 101 psi). Depending on the gas type, the flow rate has to be adapted to the current pressure
