General description

The MAS-100 CG Ex® has been specially developed for monitoring and measuring the microbiological contamination of compressed gases. The sampling method is based on the tried-and-tested Andersen impaction principle and accommodates the use of standard 90 to 100 mm Petri dishes. The compressed gases most commonly used in the industry are pre-programmed in the explosion proof device. The MAS-100 CG Ex® is the only instrument, which collects microorganisms under pressure and initiates automatic decompression after the collection cycle, thus preventing a sudden drop in pressure from damaging the microorganisms. The device is mobile, easy to use and powered via an integrated rechargeable battery. MAS-100 CG Ex® compressed gas microbial air sampler includes two sensors, one to measure mass flow and the other for pressure. The unit is pre-programmed for compressed air, nitrogen, carbon dioxide, argon and oxygen. Due to our unique mass flow sensor technology, after validation only a mathematical correction factor is required to sample other gases. The system measures the inflow of the gas and regulates it to a constant value of 100 liters/min and pressure built up ranging from 1.5 to 10 bar absolute. For low gas flow pipelines, a flow rate of 50 liters/min can be selected. The sampling head can be sterilized, and the instrument is an apparatus of category 3 according to EN 600079-14:1997. It can only be used in Zone 2 for gas groups IIA, IIB, IIC, comprising flammable substances which pose an explosion hazard in the temperature classes T1 to T6.


The MAS-100 CG Ex® is suitable for microbial monitoring of compressed gasses, such as air, nitrogen, carbon dioxide, argon, oxygen and others. The microbial air sampling devices are extensively used in Pharmaceutical and Personal care industries as well as Food, Beverage and Environmental applications.
