Description
Summary:In another gas phase study, Shutov and colleagues [13] demonstrate a non-linear optical spectroscopic technique, termed Femtosecond Adaptive Spectroscopic Technique Coherent Anti-Stokes Raman Scattering (FAST CARS), to quantitatively map species’ concentrations. The comparison of two methods—Linear Discriminant Analysis (LDA) and Quadratic Discriminant Analysis (QDA)—revealed better performance of the QDA when applied to the Raman spectra. [...]liquid–solid interactions can also be used in a chemical sensing, in particular using surface-enhanced Raman scattering (SERS) spectroscopy, where the plasmonic enhancement of an electromagnetic field in the presence of nanostructured metal surfaces is utilized. [...]a growing number of industries are realizing the potential of optical methods in terms of process analysis and material characterization. [...]it is foreseeable that the area of optics and spectroscopy for fluid characterization will experience further growth and will see fascinating new applications in the near and distant future.
