| Abstract: | This paper described the efforts made to determine volatile halohydrocarbons and chlorobenzene simultaneously by purge and trap GC. The experiment involves HP 1 silicon melting capillaries of big caliber and an ECD detector when samples are trapped by means of purge and trap. The results of analyzing samples of surface water have showed satisfactory measuring accuracy and repetition. |
