摘要
目的探讨以毛细管气相色谱法测定工作场所空气中的二聚环戊二烯。方法采用活性炭管采集,毛细管色谱柱分离的气相色谱测定方法。结果30m FFAP毛细管色谱柱对二聚环戊二烯的分离效果好于现行填充柱,可同时对共存物苯、甲苯、二甲苯、苯乙烯进行分离测定。方法的精密度、检测限等各项方法学指标均能达到《车间空气中有毒物质监测研究规范》的要求。结论该方法可完全适用于工作场所空气中二聚环戊二烯的测定。
[ Objective] To explore the application of capillary gas chromatography in the determination of dicyclopentadiene in the Air. [Methods] Capillary gas chromatography was applied to collect samples with active charcoal tubes and separate with capillary columns. [ Results] The effect of dicyclopentadiene separation using 30 m FFAP capillary column was proved to be better than using the current packed column; the methodological indexes like the precision and detection limit all accorded with the requirement in the ＂Criteria for the Toxic Substance Surveillance in the Air of the Workplaces＂. [ Conclusion] This method is applicable for the determination of dicyclopentadiene in the air of the workplaces.
