摘要
A method of identifying the presence of heroin in an impure heroin composition which contains heroin and at least one fluorescent contaminant which interferes with a Raman signal from the heroin. The method may include contacting the mixture with a solvent such as an alcohol, then contacting the resulting alcohol composition with a SERS surface. The surface may then be exposed to laser light from a hand-held Raman spectrometer to detect a Raman signal from the heroin. An apparatus for performing the method is also provided.
