摘要

采用岛津公司AOC-6000+GCMS-TQ8040带多功能自动进样器的三重四极杆串级气相色谱质谱仪结合异味分析数据库(Off-flavor Smart Database),建立了异味分析系统对饮用水中150种异味物质筛查方法.本文比较正常水样和异常水样分析所得的数据,在异常水样中检测到8种异味成分,利用数据库中标准曲线进行半定量的分析,与臭气阈值进行比对,最后确定了6种异味成分.
        In this paper, the method for analysis of 150 odor substances in drinking water were established by using the Shimadzu GCMS-TQ8040 gas chromatography-tandem triple quadrupole mass spectrometry and AOC-6000 multifunctional automatic sampling device combined with odor substances database of Off-flavor Smart Database. Normal and abnormal water samples were analyzed separately and the results were compared. Eight candidate components causing odor were identified. Semi-quantitative analysis was carried out using standard curve generated in the database. The estimated concentration was compared with odor threshold. Finally, six odor components were found. The method is simple, convenient, fast and suitable for the screening of odorous substances in drinking water.
