The development and application of dual-comb spectroscopy in analytical chemistry

Analytical chemistry plays an important role in the qualitive and quantitative analysis for molecules in the various circumstances, especially for the high-resolution analysis. The dual-comb spectroscopy (DCS) technology with the characteristics of high resolution, high sensitivity and instantaneous sampling exhibited a great potential in high-resolution in-situ spectral methods and has been active in the fields of spatial ranging, air composition analysis, reaction monitoring and so on. In this review, we will summarize the principle of DCS according to the different wavelength coverage and overview the applications of DCS in analytical chemistry.
