Abstract

Photoacoustic spectroscopy (PAS) is typically used for the detection of trace gases. However, there are a number of applications where highly concentrated mixtures need to be analyzed. In some cases especially the isotopologic composition of certain hydrocarbons needs to be determined. We present PAS-based isotopologic analyses of two digit percentage-level methane concentrations in nitrogen and its AI-based evaluation. The investigation allows conclusions to be drawn about the extent to which PAS is suitable for an isotopologic analysis of undiluted natural gas-like mixtures.
