Abstract
Mass spectrometric sensitivity data for the compounds cholesterol, cholestane, DDT, decafluorotriphenylphosphine, morphine, LSD and methyl stearate have been developed over a period of time and under a variety of conditions. This information is presented on both a relative and an absolute basis. With the exception of morphine, relative sensitivies were reproducible to within a factor of three over a six month period. This reproducibility facilitates quantitation and a single standard can be used for calibration of organic compounds from various classes. Detection limits of 50 femtograms for LSD are realized for samples introduced via the direct inlet probe.
