Gas analysis

Do you want to analyze a gas sample to find out its composition? Calnesis performs this type of measurement with different analytical techniques.

A gas analysis consists of the identification and quantification of the compounds present in the latter. Depending on the chemical family of the compounds to be analyzed, the methods to be implemented are different. It is therefore preferable to know the compounds a priori present in order to limit the analyzes carried out to what is really necessary. Otherwise, the analysis can be carried out in a broader way, which generates more analytical work and therefore much higher costs.

Gas analysis techniques

Here is a non-exhaustive list of usable analysis techniques.

Experimental analysis technics usable for gas analysis
  • GC
  • MS
  • microGC
  • TCD
  • Storage interface

Calibration for quantitation

The quantification of compounds sometimes requires the purchase of standards for each of the compounds, when they exist. Otherwise, the quantifications can be carried out in an estimated way, by considering the calibration data of chemically similar compounds.

The analysis of the composition of a gas sample often requires knowing beforehand the type of compounds expected because the analytical means used must be adapted to these compounds.
