Raman spectroscopy is used in pharma manufacturing and law enforcement to inspect pharma evidence in the field, but compact Raman spectrometers are a couple of orders of magnitude more expensive than this consumer device. Also, you really need an analytical chemist to interpret the data. Raman is hard.<p>NIR spectroscopy, which is what this product uses, isn&#x27;t very sensitive and wouldn&#x27;t be a good choice to look for trace contaminants even on quality instrumentation.
