利用国产ZHD-01S气相色谱-质谱仪(北京分析仪器厂制)进行地下水中六六六主要异构体的色—质测定,其工作条件为:不锈钢柱150×0.3cm,固定液4％OV-17,担体Chromsorb W(60～80目)。载气:氦,流量20毫升/
The colorimetric determination of BHC in groundwater was carried out using a domestic ZHD-01S gas chromatograph-mass spectrometer (Beijing Analytical Instrument Factory). The working conditions were: stainless steel column 150 × 0.3cm, fixative 4% OV -17, Carriers Chromsorb W (60 ~ 80 mesh). Carrier gas: helium, flow 20 ml /
