Comparative Analysis of Algorithms for Selection of Spectral Channels to Measure Gas Concentrations in Multi-component Mixtures Using Method of Optical and Acoustic Spectroscopy

Algorithms of the spectral measurement channels selection for the laser optical and acoustic gas analyzer, destined for the quantitative gasanalysis of multi-component gas mixtures, are compared. Advantages and drawbacks of various algorithms are considered. It is shown that the offered technique of the spectral measurement channels selection takes into account qualitatively all the main factors, effecting the gas analyzer operation, and is the most preferred one from the standpoint of the fast analysis implementation. The obtained set of wavelengths is substantiated physically and is quite suitable for the quantitative analysis of multicomponent mixtures, which is confirmed by the mathematical simulation.
