A device was developed to determine the quality of alcohol in a corked bottle.
Specialists of the University of Manchester created a detector to determine the quality of alcohol, called SORS.
Principles of operation of the device Raman spectroscopy. The laser beam passes through the liquid, after which special sensors analyze the oscillations of the radiation frequency. Different substances interact with photons in different ways, therefore, the light in molecules can be scattered non-uniformly. The result is a so-called drink map.
The authors of the instrument for the texts selected 150 different alcoholic beverages, 40 of which were of inadequate quality, that is, fake. At the first stage, the alcohol was checked in a blocked form, after checking in it a small amount of methanol was added. The SORS instrument unmistakably identified the diluted samples, even though all the bottles were made from different glass. In addition, the unit was able to distinguish between varieties of strong alcohol.
Currently, the problem of counterfeit alcohol is very serious. Counterfeit drinks, universally represented on the shelves, can not be distinguished from these without conducting special research. In order for each consumer to be able to easily distinguish whether he has acquired quality alcohol or not, and devices similar to SORS are needed. It remains to hope that in the very near future, the authors of the study will move from experimental experiments to the process of actual introduction of the novelty into real life.
