Laboratory Assist Gases

The right gas and the right purity for your specific laboratory analyser application.

The basics of your day to day analytical work

Nitrogen, Hydrogen, Synthetic air and Helium are the “Top 4” gases used in analytical instruments. Argon, Carbon dioxide and Oxygen are used in more specific applications.

The important thing is not the gas: it is what you will be able to do with it.
