Analysis of Leachate from Water Supply Equipment Using Purge and Trap GC/MS

Water supply equipment refers to materials or equipment used in water supply facilities. The quality of these materials is required to conform to the standards designated by ordinances from the Ministry of Health, Labour and Welfare, as per "tests related to the quality of materials in equipment" (notification no. 45 by the Ministry of Health, Labour and Welfare in 2000). This, in turn, was prescribed on the basis of "ministerial ordinance regarding the technical standards for water supply facilities" (ordinance no. 15 by the Ministry of Health and Welfare in 2000). The six components shown in Table 1 are configured in the purge and trap (PT) GC/MS method. They differ significantly in terms of boiling point and solubility in water, so the method for the PT system is divided into two parts. However, since the sample volumes and trap tubes are completely the same in the two PT methods, system switching is not required, which means that consecutive analyses can be performed efficiently. This Data Sheet presents the results of an investigation regarding the ease of quantifying the components in the leachate from water supply equipment via a purge and trap GC/MS.
