Apix, in situ analysis of industrial gases and liquids

Published on 15 December 2022
​Real time, in-process measurement for higher yields and better product quality.

Apix Analytics is bringing industrial gas and liquid analysis to a wide market with its miniaturized gas chromatography modules. They are half the price and ten times the resolution of laboratory equipment.

The Chrompix, an analysis system that embeds up to four plug & play chromatography analysis cartridges.

Apix Analytics leverages advanced silicon technologies developed by the CEA and Caltech and protected by 25 patents to produce miniaturized gas chromatography modules of less than a liter. With the company’s continuous on-site analysis solution, users no longer need to send samples to a lab and wait for the results to come back—they can optimize their processes in real time.

The startup’s analyzers are simple enough to be used by anyone. They detect all gases and liquids, from hydrogen to heavy oils—a versatility unmatched on the market. These compact and competitive analyzers can carry out quality controls, verify the correct level of odorization of natural gas, or calculate caloric value for pricing purposes.

Apix Analytics is developing new generations of multi-gas detectors with the CEA. Its customers include major energy companies such as Air Liquide, Engie, and TotalEnergies.
