Certified gas mixtures

These mixtures are prepared using gravimetric and volumetric techniques and are then controlled by comparison to primary reference standards. These preparations and their analyses are based on international standards such as ISO 6142 and ISO 6143.
SIAD actively participates in national and international work-groups on analytical techniques in the gaseous phase.

The most common applications are in:

  • chemical laboratories, general and quality control laboratories
  • process control analysers and chromatographs
  • environmental and work-station monitoring
  • toxic and flammable gas detection.
