Gas chromatography

Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds. Air Liquide's ALPHAGAZ™ pure gases are guaranteed to have low impurities. And ALPHAGAZ™ Mix provides four product classes of mixtures, meeting your accuracy and blend tolerance requirement.

Scott™ brand gas mixtures, based on the level of accuracy you require, meet and exceed typical LCMS and GCMS requirements, and gas mixture concentrations are certified to protect instruments. Both ensure peak performance.
