Raman spectroscopy is an analytical technique which can be used both qualitatively and quantitatively. Qualitatively, Raman spectroscopy can be used for whisky analysis to ensure it does not contain methanol, a toxic alcohol which can be fraudulently used in alcohol sales to boost profits. In this application note, Edinburgh Instruments detail the quantitative use of Raman spectroscopy to determine ethanol content in samples of whisky, demonstrating that samples can be analysed rapidly making Raman spectroscopy an ideal technique for ensuring whisky is being sold safely and legitimately.
