Spectrofluorometric analysis of illicit drug samples, employing a corrected excitation spectrofluorometer.

Spectrofluorometry, because of its high sensitivity, has developed into one of the most useful analytical methods available to the forensic chemist for certain ilicit drug samples encountered in small amounts. The corrected excitation spectrofluorometer adds to the usefulness of this technique by generating more reproducible results with greater sensitivity. The excitation spectra are in better agreement with absorption spectra, and the need to recalibrate constantly with standard solutions in order to perform quantitative analysis can be minimized. Lysergic acid diethylamide and a fluorophore of morphine related drugs were examined employing a corrected excitation spectrofluorometer. Data is presented substantiating the advantages of a corrected instrument.
