Online Detection of Clear Point in Esterification Process of Polyester Production Based on Raman Spectroscopy
In this article, an online Ｒaman analysis system with 1064 nm as the laser wavelength was set up to collect continuously the spectra of the esterification reaction between terephthalic acid( PTA) and 1, 3-propanediol (PDO) to create poly (tri-methylene terephthalate) ( PTT), while using the Savitzky - Golay algorithm to make baseline correction on the collected spectra.

What applications can The Raman spectrometer be used in the identification of physical evidence?
Raman spectroscopy is a spectral analysis method based on the Raman scattering effect, which can determine the composition of substances very sensitively. Compared with infrared spectroscopy, Raman spectroscopy has a wider measuring range, which can be extended to 100cm-1, and more spectral information of substances can be obtained through Raman spectroscopy.
