Description
| - A study has been carried out of acetonitrile in exhaled breath and in the headspace of urine from several cigarette smokers and several non-smokers using selected ion flow tube mass spectrometry, SIFT-MS. The ion chemistry involved in the detection of acetonitrile in the gas phase by SIFT-MS using H3O+ ions is outlined. Further to this, experiments have been carried out to determine the Henry's Law partition coefficients for dilute aqueous solutions of acetonitrile, which allow the determination of liquid phase urinary acetonitrile concentrations from headspace concentrations. The results of this study show that acetonitrile is readily detected by SIFT-MS in the breath and urinary headspace of smokers at levels dependent on the cigarette consumption, but is practically absent from the breath and urine headspace of non-smokers. Exploiting the measured values of the Henry's Law partition coefficients, the urinary phase concentrations have been deduced.
