Implementation and evaluation of an analytical method using spectral (laser) analysis in cavities to analyze complex gaseous effluents

Summary

The analysis of complex gases (flue gases, biogas, etc.) still poses a number of analytical difficulties, particularly when it comes to measuring minor constituents. This experimental project will enable us to assess the relevance of new spectral techniques of the OF-CEAS* type. As this type of technology is potentially a technological breakthrough, this work provides feedback that is not yet widely available. Following a bibliographic phase, field experiments were carried out under industrial and laboratory conditions. Feedback from the first users completed the critical analysis. The result is a comprehensive report that assesses the operational potential of these techniques compared with others available.
