PG - 194-204 LID - 10.1016/j.jchromb.2008.03.029 [doi] AB - A liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry (LC-APCI-MS/MS) method for quantification of 10 amphetamine-related analytes in 1g meconium is presented. Specimen preparation included homogenization and solid-phase extraction. Two multiple reaction monitoring transitions were monitored per analyte. Ten and 1 microL injection volumes permitted quantification up to 10,000 ng/g, with sufficient sensitivity to quantify minor metabolites. Lower limits of quantification ranged from 1.25 to 40 ng/g. Precision was less than 14.2%, with accuracy between 79 and 115%. Meconium from a methamphetamine-exposed neonate was analyzed. Metabolites p-hydroxymethamphetamine, norephedrine and 4-hydroxy-3-methoxymethamphetamine were identified in meconium for the first time.
