Optimized procedures for simultaneous quantitation of low concentration levels of morphine and codeine in urine using gas chromatography–mass spectrometry

Optimized procedures for simultaneous quantitation of low concentration levels of morphine and codeine in urine using gas chromatography–mass spectrometry

Background: Detection techniques with high specificity, precision and accuracy are required for evidence of illicit drug intake. The study aim was to develop a low-concentration drug testing method for morphine and codeine in urine samples using gas chromatography-mass spectrometry (GC-MS) to estab...
