GMP Gas Analysis for Nitrogen, Compressed Air, Oxygen, and Ammonia

Comprehensive sampling and testing—reliable and GMP-compliant.

The quality of gases used in pharmaceutical applications has a direct impact on the safety of your products and processes. This makes it all the more important to reliably test their purity and document the results in a traceable manner. To this end, Infraserv Höchst combines in-depth analytical expertise with practical operational experience and a clear understanding of your GMP requirements.

We offer comprehensive sampling and GMP-compliant analysis for gases used in the pharmaceutical industry—specifically nitrogen, compressed air, oxygen, and ammonia. The tests are based on the applicable requirements of the European Pharmacopoeia (Ph. Eur.) as well as your application-specific specifications.

Our trained specialists perform the sampling directly on-site; for ammonia, our services are limited to analytical testing.

Depending on the type of gas and the agreed-upon testing plan, our services include the following test parameters:

  • Oxygen content
  • Carbon monoxide content
  • Carbon dioxide content
  • Nitrogen content (vol. %)
  • Identity testing
  • Water content
  • Oil content
  • Total yeast and mold count (TYMC)
  • Total aerobic microbial count (TAMC)
  • Total anaerobic microbial count
  • Particles ≥ 0.5 µm
  • Particles ≥ 5 µm
  • Ammonia content
  • Water content in ammonia

Benefits for You

  • Comprehensive GMP Testing: All relevant test parameters for nitrogen, compressed air, Oxygen, and ammonia from a single source
  • Validated Methods: Appropriate testing methods that comply with current Pharmacopoeia requirements
  • Quality Assurance: Analytical testing to ensure the quality of your product and process gases
  • Traceability: GMP-compliant documentation of the tests

Our Technical Equipment and Work Methods

  • Modern analytical technology, including gas chromatographs (GC), particle counters, and Karl Fischer analyzers
  • Standardized operating procedures (SOPs) and GMP-compliant processes
  • Sampling performed on-site by trained specialists, including in cleanrooms

Typical Applications

  • Pure gas supply for pharmaceutical production facilities
