[The use of a method of solid-phase extraction for sample preparation in the identification of unknown substances by IR spectroscopy].
Identification of synthetic narcotics is difficult because they do not possess any apparent individual signs and the specimens are contaminated with various fillers and additives, which rules out investigations by infrared spectroscopy, widely used in expert practice. Use of solid-phase extraction during preparation of samples helps prepare highly purified samples which can be further identified by IR spectroscopy. The authors present the protocol of identification of unknown substances and recognition of narcotics and describe methods for identification of some confiscated narcotics (methadone, MDA, phencyclidine, methaqualone, codeine, ethylmorphine, cocaine, etc.).
