The article evaluates the ProRaman instrument with laser excitation from Enwave Optronics.

The article focuses on the use of the Raman spectroscopy to determine the presence of low concentration methanol in alcohol. It discusses the laboratory method for the compositional analysis of alcohol in which a 40 percent ethanol-water solution was prepared for measuring methanol concentration using Raman spectrometer with laser excitation at 785 nanometer wavelength.

The article discusses an approach for determination of low concentration of methanol in alcoholic beverages through Raman Spectroscopy. The advantages of Raman spectroscopy for compositional analysis of methanol in alcohol as well as identification of food adulterants are discussed. It mentions that Raman spectroscopy provides a cost effective alternative for detection of low concentration of methanol.
