Development of a procedure for the gas-chromatographic determination of vinyl chloride and 1,2-dichloroethane in blood with the use of headspace analysis

摘要

A procedure for the determination of the weight concentrations of vinyl chloride and 1,2-dichloroethane in blood over the range of 0.1-2.0 μg/cm ~3 was developed. The procedure is based on a static version of gas-chromatographic headspace analysis. The determination was performed on a column packed with a Chromaton N-AW-DMCS sorbent with 15 wt % Apiezon L using flame-ionization detection. The relative error of the procedure was no higher than 20%.
