  • Page 15: Instrument Description

    2. INSTRUMENT DESCRIPTION 2.1. APPLICATION/INTENDED USE The microbial compressed gas sampler is a highly accurate instrument used for tak- ing samples from compressed gases, such as air, Nitrogen (N ), carbon dioxide ), Argon (Ar) or a customer-defined gas (mixture) to assess the colony forming unit (CFU) count in a specific gas amount.

  • Page 16: Mass-Flow-Based Sampling Of Gas Volume

    2.3.4. MASS-FLOW-BASED SAMPLING OF GAS VOLUME The instrument is equipped with a mass flow sensor in order to measure the amount of gas sampled, which is represented as a standardized volume. In this way, samples performed under different conditions (temperature, ambient pressure, altitude from sea level, etc.) are reproducible and comparable.
