Morphine and codeine have been identified and measured in a human urine matrix using high-field asymmetric waveform ion mobility spectrometry (FAIMS) in a tandem combination with electrospray ionization (ESI) and mass spectrometric (MS) detection. The addition of helium to the nitrogen carrier gas resulted in a substantial improvement in the sensitivity of the ESI-FAIMS-MS instrument for the determination of morphine and codeine. Limits of detection in human urine were 60 ng/mL for morphine and 20 ng/mL for codeine with no clean-up, derivatization, or chromatographic separation of the sample prior to analysis.
