内容記述 |
We have developed a simple and sensitive method for determining acetonitrile and propionitrile in human whole blood using capillary gas chromatography (GC) with cryogenic oven trapping. After heating 0.5 mL of a whole blood sample containing both nitriles and 0.5 mL distilled water in a 7-mL vial at 75℃ for 15min, 5 mL of the headspace vapor was drawn into a 10-mL syringe and injected to GC with a flame thermionic detector. A sharp peak was obtained for acetonitrile at -10℃ of the initial oven temperature. The extraction efficiencies for acetonitrile and propionitrile were 0.27 and 0.40%, respectively. For quantitation of acetonitrile, propionitrile was used as internal standard, and vise versa. The calibration curves for both compounds gave good linearity in the range of 0.2-6 μg/mL whole blood. The detection limits (signal to noise ratio = 3) were 0.05μg/mL for acetonitrile and 0.01μg/mL for propionitrile. The coefficients of intra-day variations were 1.0% at 0.4μg/mL and 1.7% at 2μg/mL for acetonitrile; 7.1% at 0.4μg/mL and 1.0% at 2 μg/mL for propionitrile. Thus, this method can be applicable for determining these nitriles in whole blood samples in acute and chronic intoxication cases. |
