GCD quantitation of opiates as propionyl derivatives in blood.
We describe a method using a gas chromatograph with electron ionization detection (GCD) for the simultaneous determination of morphine, codeine, 6-monoacetylmorphine, ethylmorphine, and dihydrocodeine in blood. The method employs propionic anhydride in the presence of triethylamine to propionylate free hydroxyl groups of the opiates in blood. The quantitation is achieved by using GCD with selected ion monitoring of the two most characteristic ions for each analyte. The quantitation limit was 0.01 mg/L and the linearity was 0.01-10 mg/L for dihydrocodeine, ethylmorphine, and 6-monoacetylmorphine. For the other investigated opiates, the quantitation limit was 0.025 mg/L and linearity was 0.025-10 mg/L. The intraday relative standard deviation (RSD) varied from 7.2 to 10% at the 0.5 mg/L level, and the day-to-day RSDs varied from 7.5 to 11% at the 0.85 mg/L level.

Subcritical fluid extraction of opiates in hair of drug addicts.
Hair analysis is a useful complement to blood and urine analysis in forensic science, but current procedures are tedious and time consuming. Owing to the difficulty of having a sufficient amount of hair in order to perform the optimization of the extraction method, standard hair was made and the procedure is described. The spiking method is reproducible and linearity can be obtained. Subcritical fluid extraction of opiates from standard and drug addicts' hair was optimized (extraction phase composition, extraction time, etc.) and compared with other extraction techniques (basic and acid hydrolysis, organic solvent and enzymatic digestion) followed by solid-phase extraction. Recovery, coefficient of variation, linearity, detection limits and quantification limits for the subcritical fluid extraction of opiates in hair are described.
