Gas Testing, Analysis and Certification

Process gases are used in production and processing in many industries. Analysis and measurement of these gases is essential for ensuring safety, meeting process control demands and complying with regulations. SGS provides testing, analysis and certification services for industrial, medicinal and ultra high purity gases. This can include supplying custom analytical systems to enable continuous monitoring onsite.

ISO 14644 is the international standard for cleanroom classification and environmental monitoring. Part 1 (ISO 14644-1) sets limits for airborne particle concentrations. In pharmaceutical production, process gases like compressed air and nitrogen must meet similar standards for particle cleanliness.

Yes. We perform ISO 14644-aligned testing for viable and non-viable particles in process gases, using particle counters capable of detecting and quantifying particles ≥0.5 µm and ≥5 µm, as required.

EudraLex Volume 4 outlines good manufacturing practice (GMP) for pharmaceuticals in the EU. Annex 1 specifically requires that compressed gases in contact with sterile products be regularly tested for both viable and non-viable particles to ensure product safety.

ISBT certification ensures that beverage-grade gases meet the strict purity and safety standards defined by the International Society of Beverage Technologists. It is required by major bottlers like Coca-Cola and PepsiCo, and other beverage producers worldwide.

Yes. Our ISO 8573-1 service includes testing for particles, water (humidity and dew point), oil content and microbiological contamination in compressed air systems.

It depends on your industry and risk level, but many companies perform testing annually or semi-annually. For critical applications like food, beverage or pharma, more frequent testing may be recommended.

A third-party QA/QC provider is an independent organization that verifies compliance against specifications or standards. In the semiconductor industry, third party QA/QC providers are critical for achieving the quality and safety standards required during construction and commissioning.

QA/QC verifies construction quality before energization, while process qualification validates that energized systems operate according to specifications. Both steps are critical for ensuring safety, quality and efficiency in semiconductor operations. We can mobilize specialized equipment for the process qualification of bulk gas installations (storage tanks, purifiers, filtration and/or distribution systems).
