Study of the Extraction of LSD from Illicit Blotters for HPLC Determination
The effect of different parameters (extraction method, temperature, time, solvent) on the extraction efficiency of LSD from impregnated papers has been investigated. Designed experiments have been applied according to the Plackett-Burman method. For the quantitative determination of LSD reversed phase ion-pair chromatography has been used with UV detection. The experimental conditions assuring maximal LSD recovery have been determined, as well as the constant and proportional bias of the extraction procedure elaborated.
