The need to rapidly analyze trace narcotic samples for screening or confirmatory purposes is of increasing desire to the forensic, homeland security, and criminal justice sectors. This work presents a novel method for the detection of trace drugs and metabolites, using a thermal desorption direct analysis in real time mass spectrometry configuration (TD-DART-MS). A variation on traditional DART, this configuration allows for the analysis of a sample directly off of swipe material, independent of the DART source. Over thirty trace narcotics were analyzed and could be rapidly differentiated and searched. Sensitivity for these compounds, under non-optimized conditions, ranged from single nanograms to hundreds of picograms.
