Dual-comb spectroscopy's creation and use in analytical chemistry

Bryan Walker

In both qualitative and quantitative analyses of molecules in a variety of contexts, analytical chemistry particularly high-resolution analysis plays a significant role. The dual-comb spectroscopy (DCS) technology has been active in the sectors of spatial ranging, air composition measurement, reaction monitoring, and other high-resolution in-situ spectrum approaches. It has the advantages of high resolution, high sensitivity, and instantaneous sampling. With regard to the various wavelength coverage, we will summarise the DCS principle in this review and give an overview of its uses in analytical chemistry.
