LCMS Method for Spiked Urine Sample

LSD and codeine may be present in Urine samples and methods are needed for their detection in these matrices. The extracted Ion Chromatograms (EICs) for both analytes are shown in the figure and illustrate excellent chromatographic as well as Mass Spectral Separation. The Method in this AppNote produces high Efficiency for both Peaks.

Note: Lysergic Acid Diethylamide (LSD) was synthesized by Swiss chemist Albert Hofmann while researching Ergot Alkaloid Derivatives. It is highly potent and produces significant psychedelic effects when ingested. It is currently a Schedule I drug in the U.S. Codeine is an opiate used for analgesic, antitussive, and other effects. It may be obtained from over-the-counter formulations like Cough Syrup and therefore has potential for abuse.
