AN 9591 - Screening Controlled Substances Using the Near-infrared Fourier Transform Raman Technique


The FT-Raman technique is very sensitive to the presence of a wide range of controlled substances and has several unique attributes which are invaluable when screening seized evidence for the presence of these compounds. The method allows materials to be quickly analyzed without removing them from the sealed evidence bags in which they are collected eliminating cross contamination or sample contact. An unknown ‘sealed’ compound can be analyzed in less than 30 seconds by referencing a library of known standard samples. Nicolet has developed a library of over 200 compounds for this analysis.
