摘要
进行1,2-二氯乙烷作业环境检测的气相色谱测定方法学研究,通过将填充柱改为毛细管色谱柱得到的1,2-二氯乙烷检出限,远远小于GBZ/T 160.45—2007中的给出值,从而推导出修改GBZ/T 160.45—2007中规定的1,2-二氯乙烷采样体积的可行性。修改后的试验方法将降低采样和检测成本。
The objective of this study is ro investigate the detection method of 1,2-dichloroethane by Gaschromatography. When using packed column instead of capillary column, 1, 2-dichloroethane detection limit is far less than the value in GBZ/T 160.45-2007 method. So modification method is deduced for 1, 2-diehloroethane sampling volume in GBZ/T t60.45-2007 method. Modification of the test method will greatly reduce the sampling volume and testing cost.
