Primary Reference Gas Mixtures (PRGM)

PRGMs are the highest quality gas mixtures available for use by commercial organisations. They have the lowest achievable uncertainties providing the most accurate realisation of the amount of substance fraction. Such mixtures are used by ISO 17025 accredited laboratories who need to establish reference values for internal gas standards. EffecTech’s PRGMs are available under the ISO 17025 scope only.

Mixtures are prepared and certified by high precision gravimetry and individually verified analytically by a traceable comparison method and in accordance with ISO 6142-1:2015.
