Receiver operating characteristic (ROC) curve framework was employed to investigate the trace detection of fentanyl and fifteen fentanyl-related compounds relative to environmental background interferents.
We present a new highly sensitive technique for the detection of explosives directly from the surface using laser desorption-corona discharge-ion mobility spectrometry (LD-CD-IMS).
The discriminative potential of an ion mobility spectrometer (IMS) for trace detection of illicit narcotics relative to environmental background was investigated with a receiver operating characteristic (ROC) curve framework.
