【Abstract】 In this paper, the elementary principle of the cold vapour mercury detector for model JD-502 and its design are described briefly. Furthermore, the construction,the property and the application of the detector are discussed in detail. In the case where the JD-502 used as a detector in combining with the gas chromatographic column, the practical absolute sensitivity indetecting chloromethyl mercury is found to be about 1×l0^-11g.更多还原
