摘要
An LC-MS/MS based screening method for cannabinoids, opiates, amphetamines, cocaine, benzodiazepines and methadone was developed for the analysis of human serum, urine and post-mortem blood and discussed as an effective alternative to immunoassay based screening methods. Two mass spectrometric systems with differences in sensitivity common known were used for method validation. A simple protein precipitation was applied for a sample volume of 100 lL analysed using a Luna 5 mm C18 (2) 100 A, 150 mm x 2 mm analytical column and two mobile phases consisting of A (H2O/methanol = 95/5, v/v) and B (H2O/methanol = 3/97, v/v), both with 10 mM ammonium acetate and 0.1% acetic acid. The results achieved demonstrated that the method presented fulfils the recommendations for qualitative screening methods and can be applied successfully in the analysis of real samples.
