Multivariate Analysis as a Tool to Identify Concentrations from Strongly Overlapping Gas Spectra

Multivariate Analysis as a Tool to Identify Concentrations from Strongly Overlapping Gas Spectra

Show other versions (1)

We applied a multivariate analysis (MVA) to spectroscopic data of gas mixtures in the mid-IR in order to calculate the concentrations of the single components which exhibit strongly overlapping absorption spectra. This is a common challenge in broadband spectroscopy. Photoacoustic (PA) measurements...
