Quantitative enantioselective Raman spectroscopy.

Universal enantioselective discrimination by Raman spectroscopy.

Distinguishing between the enantiomers of chiral substances and their quantification is an analytical challenge, in particular in the pharmaceutical and biochemical sectors. A Raman spectroscopic method for discrimination of enantiomers is proposed. Advantage is taken of the polarization properties when Raman scattering occurs in an optically active medium. It is shown that a conventional polar...

Quantitative Biological Raman Spectroscopy for Non - invasive Blood Analysis

Classification and Quantitative Analysis of Azithromycin Tablets by Raman Spectroscopy and Chemometrics

Raman spectroscopy has been proven a noninvasive technique with high potential in pharmaceutical industry. In this study, micro Raman technique and chemometric tools were used for identification of azithromycin (AZM) tablets by different manufacturers and quantitative analysis of the active pharmaceutical ingredient (API) in the samples. Support vector machine (SVM), Bayes classifier and K-near...

Raman spectroscopy: lighting up the future of microbial identification.

Over the last decade Raman spectroscopy has become established as a physicochemical technique for the rapid identification of microbes. This powerful analytical method generates a spectroscopic fingerprint from the microbial sample, which provides quantitative and qualitative information that can be used to characterize, discriminate and identify microorganisms, in both bacteria slurry and at t...

Laser Micro-Raman Spectroscopy of CVD Nanocrystalline Diamond Thin Film

Laser micro-Raman spectroscopy is an ideal tool for assessment and characterization of various types of carbon-based materials. Due to its special optical properties (CrN) coated stainless steel substrates. NCD films have been investigated by laser micro-Raman spectroscopy. The fingerprint of diamond based materials is in the spectral region of 1000-1600 cm-1 in the first order of Raman scatter...
