本文用自己组装的四臂热导池气相色谱仪试验了分析六六六(BHC)的条件。得出用1%PEG/6201。1%聚乙二醇20M/201和1%PEG20M+1%阿皮松L/201分离柱(内径4毫米),柱温175℃,以氢作载气,流速50毫升/分,进样3-4微升(1克样品溶于6毫升丙酮中),可以分离并测定甲体、乙体、丙体、丁体等四个异构体。六氯苯最低检出量为10-8克。并测定了各异构体的理论塔片数,比保留时间和分离度。一次测定可在15分钟内完成。误差±0.3%。
In this paper, we use their own assembled four-leg thermal conductivity gas chromatograph to analyze the conditions of BHC. The column (inner diameter 4 mm) was eluted with 1% PEG / 6201.1% polyethylene glycol 20M / 201 and 1% PEG20M + 1% Flow rate of 50 ml / min, injection of 3-4 microliters (1 g sample dissolved in 6 ml of acetone), you can separate and determine the body A, B, C, D and other four isomers. Hexachlorobenzene minimum detectable amount of 10-8 grams. The number of theoretical plates, specific retention time and resolution of each isomer were determined. A determination can be completed within 15 minutes. Error ± 0.3%.
