Gas analysis

Objective of the analysis

Gas analysis determines the qualitative and/or quantitative composition of a gas sample. This analysis applies to simple or complex mixtures and can be targeted (known compounds) or exploratory (broad analysis). It is essential in many industrial sectors for:

• Controlling the quality of air , modified atmospheres or technical gases
• Evaluate emissions of solid or liquid materials
• Verify regulatory or environmental
• Characterize the products resulting from chemical or thermal

Available analytical techniques

Depending on the nature of the compounds to be identified or quantified, different methods are used:

• Gas chromatography (GC) : separation of volatile compounds
• GC-MS (mass spectrometry) : precise identification of compounds
• Infrared (IR) or UV-Vis : functional recognition
• Absorption spectroscopy : measurement of the concentration of specific gases
• Semi-quantitative analysis : comparison between samples without exhaustive calibration

When the compounds are known in advance, the analysis is more targeted, faster, and more economical. In the absence of prior data, a exploratory approach can be considered.

Common applications

• Analysis of industrial gases, waste gases or medical gases
• Purity control and impurity detection
• Monitoring of thermal or oxidative degradation (materials, polymers)
• R&D studies on the kinetics of degassing or volatile emissions
• Verification of the conformity of modified atmospheres in the agri-food sector

Affected matrices

• Samples of pure or mixed gases
• Gases emitted by solids , liquids , or complex formulations
• Atmospheres in closed systems (packaging, test chambers)
