Abstract

Gas chromatography Fourier transform infrared spectroscopy (GC/FT-IR) has been examined as a new forensic drug identification technique. The method is found to be specific for many closely related isomers including cocaine and pseudococaine or phentermine and methamphet-amine. Distinguishing some isomers may require spectral subtraction or examination of band positions. The useful range of GC/FT-IR sensitivities was determined to be from 50 to 500 nanograms per component.
