Abstract: Objective To establish a method for the determination of 24 volatile organic compounds(VOCs) in whole blood by headspace-gas chromatography-mass spectrometry(GC-MS). Methods The VOCs in blood samples were separated by column after headspace injection,and detected by GC-MS. Results The linear relationship of 24 kinds of VOCs in blood was good in the range of 10.0-3 000.0 ng/mL,the correlation coefficients were higher than 0.999 4,the detection limit was 0.2-10.0 ng/mL,the recovery rate was 78.7%-116.4%,and the relative standard deviation was 0.9%-8.3%. The samples could be preserved at 4 or -25 ℃ for three days. Conclusion This method is simple,accurate,and highly sensitive,which is suitable for the detection of volatile organic compound in whole blood of occupational exposure persons and poisoning patients.
