Title: Simultaneous determination of 16 kinds of common organic compounds in the air of workplace by gas chromatography
Abstract: Objective To establish a method for simultaneous determination of 16 kinds of common organic compounds in the air of workplace by gas chromatography.Methods Organic compounds were collected with charcoal tubes,then detected by gas chromatography with FID detector after being desorbed with carbon disulfide and separated by HP-5 capillary column.Results Separating effect of 16 kinds of common organic compounds was good.The coefficient of correlation was greater than 0.999 5.The limit of detection was between 0.10 and 0.75 mg/L.The relative standard deviation was in the range of 0.3%~4.3%.The recovery was 95.2%~106.1%,and the efficiency of desorption was 77.6%~100%.Conclusion The method is simple,accurate,operational,and has improved efficiency,so it is suitable for routine daily monitoring.
