New Air Sampler Available from QM Solutions

QM Solutions is happy to announce a new addition to its range of air samplers, The MAS-100. The Merck MAS-100® Microbial Air Monitoring Systems are the most accurate examples of the Anderson impaction principle in microbial air sampling. Air is aspirated through a perforated lid with 400 holes, impacting growth media in a standard 90mm petri dish or 60mm contact plate. A state-of-the-art mass flow sensor assures a constant air flow rate (real time) of 100 L/min (except the MAS- 100 Eco) continuously regulating the flow during sample collection and automatically adjusting for variations in media fill levels and individual perforated lids as well as air density.

Four different versions of MAS-100® microbial air samplers are available for different applications each complies with the guidelines as specified in
ISO14698-1.

MAS-100® / MAS-100 Ex®

Both the MAS-100® and MAS-100 Ex® portable air samplers were designed for use in clean rooms and will not produce disturbance in a laminar flow environment. These compact yet sophisticated devices are the preferred choice for those demanding the highest quality in microbial air monitoring with the highest airflow accuracy of ±2.5%. The MAS-100 Ex® is approved for use in areas where there is an explosion risk, in accordance with SN-SEV (NIN) for zone 2.

MAS-100 Eco® - Inexpensive, reproducible, flexible and simple

This smaller, lightweight unit is great for the clean room but also air monitoring in food and beverage production areas. Offering many of the same features found on the standard MAS-100® air sampler, without the mass flow sensor. The handle doubles as a stand and an optional tripod adapter attaches to the handle for fixed applications.

MAS-100 CG Ex®

The MAS-100 CG Ex® system enables quick, easy and accurate testing of compressed gases for microbial contamination and is the only sampler approved for use in Zone 2 explosion hazard areas. The MAS-100 CG Ex® is calibrated with compressed air. Due to our unique mass flow sensor technology, only a mathematical correction factor is required to sample other gases (pre-programmed for nitrogen, carbon dioxide and argon gas).
