Abstract: |
A handheld spatially offset Raman spectroscopy (SORS) device has been used to detect fake spirits by researchers at The University of Manchester. It was able to find the six most common denaturants and four flavourings/additives used in fake spirits drinks such counterfeit whisky. SORS works by using an optical approach where lasers are directed through the glass enabling the isolation of chemically-rich information held within the spirits. Researchers demonstrated detection through multiple colours of bottles and in a variety of spirits. The laser has to be pointed at the bottle for a minute but this could get quicker in the future. |
