Collection of Microorganims in Compressed Gases using MAS‑100 CG Ex®
Description of the validation of the MAS-100 CG Ex which collects germs in compressed gasses without damaging pressure differential according to ISO 14698-1

Microbial Air Sampler Qualification MAS-100®
Comparative studies of eight different methods yielding 1022 individual results at Novartis Pharma AG undertaken in Basel, Switzerland, between 1981 and 1998 were evaluated. They show that, if meaningful statistical analyses are performed, adherence to important testing parameters such as sampling periods, culture media used, and placement of the devices, six of the eight methods examined yielded comparable cfu levels.

A comparative study of two different microbial air momitoring methods: Conventional and Sequential Sampling (SQS)
The study compares the conventional air sampling (single aspiration and impaction of air) with the sequentiel sampling (sample volume split into several fractions spread over a longer time period). Additionally drying exeriments on Petri dishes were carried out to exclude the influence of subobtimal media on colony growth. The authors came to the conclusions that: The advantages of sequential air sampling are: - The use of less Petri dishes- The possibility to monitor air over a longer observation period and in the absence of human presence (technician)- the possibility to avoid atypical environmental influences caused by the coming andgoing of an operator whose presence is unavoidable in the conventional operatingmode.
