HyGAS : Compressed Gas Microbial Air Sampler and the Proposed Revision to the ISO 8573-7 Standard for Microbial Testing of Compressed Gas.

The HyGAS Compressed Gas Microbial Air Sampler is a high-performance solution designed for microbiological monitoring of compressed gases in pharmaceutical, biotechnology, and industrial cleanroom environments. Engineered to support GMP-compliant contamination control strategies, it enables accurate detection of microorganisms in pressurized gas streams such as air, nitrogen, CO₂, argon, and oxygen. Designed for direct sampling at system working pressure (up to 9 bar), the HyGAS ensures efficient microbial recovery without compromising organism viability. Its advanced decompression and flow control technology guarantees homogeneous gas distribution onto the sampling medium, improving detection accuracy and reproducibility. Constructed from electropolished 316L stainless steel, the system features a hygienic design that minimizes contamination risks and ensures easy cleaning and disinfection. It is specifically engineered to withstand demanding industrial conditions while maintaining high sampling performance.The HyGAS operates without the need for an external power source, offering simplified installation and flexible integration into existing compressed gas systems. It supports both Petri dish and membrane sampling formats, making it adaptable to various microbiological testing protocols. With optimized d50 particle capture efficiency and a design focused on reducing shear stress, the system ensures reliable microbial collection even under high-pressure conditions. A wide range of accessories enhances usability across different applications. Ideal for sterile manufacturing, clean utilities monitoring, and compressed gas quality assurance, the HyGAS system strengthens contamination control strategies by providing reliable, efficient, and validated microbial sampling directly from pressurized gas sources. Complies with the proposed ISO8573-7 draft, for sampling direct from the gas outlet to the agar plate without restriction.
