Preliminary tests, such as color tests, provide an indication of whether a drug might be present. Then the sample is run on one or more instruments to confirm the presence of the drug. After the analysis is complete a formal report is generated for use in court. The tests used in the analysis of drug evidence may include a number of different instrumental techniques including:
Gas Chromatography/Mass Spectrometry (GC/MS)
Fourier-Transform Infrared Spectroscopy (FTIR)
