Quantitative measurement of mixtures of hallucinogens by fluorometry and phosphorimetry.

Room temperature fluorometric and low-temperature phosphorimetric analytical curves of hallucinogens in methanol/water solution have been prepared to demonstrate the absence of interference in common binary mixtures of hallucinogenic drugs. Limits of detection and linear dynamic ranges have been determined for drugs in mixtures. Mixtures containing LSD and another hallucinogen such as STP (DOM), psilocybin, mescaline, and phencyclidine have been studied. Detection limits are low, and analytical curves are linear over wide concentration ranges.
