| Abstract: | Objective To establish a method used for qualitative and quantitative determination of major components of liquefied petroleum gas (LPG) in human blood. Method LPG was added to the blood. The major components of the LPG were then detected by the artifical head-space-GC/MS including retain time amd mass-spectrogram for qualitative analysis and single-ion peak area for quantitative determination. Results The lowest limit of 7 components of LPG detected in blood ranged between 12.8-31.3ng. The lowest limit of quantitative analysis by the equipment ranged between 1.02-3.36ng. Conclusion This method is simple, convenient and accurate. |
