Lindane from liquid insecticide-fungicide formulations containing lindane with maneb can be determined by gas chromatography using 3% OV-1 or 5% SE-30 columns. Lindane is extracted with acetone, and an aliquot is diluted to volume with anhydrous methanol and injected on-column. The internal standard, diethyl phthalate, has a retention time of 6 min and lindane has a retention time of 12 min, allowing injection every 15 min. Within-laboratory analysis of 3 typical formulations indicates good precision with coefficients of variation ranging from 0.45 to 1.58%. The method can be easily adapted to other liquid or dust formulations of lindane.
含有林丹与代森锰锌的液体杀虫剂-杀菌剂制剂中的林丹，可用气相色谱法在3% OV - 1或5% SE - 30柱上进行测定。林丹用丙酮萃取，取一份稀释至一定体积的无水甲醇溶液进样。内标邻苯二甲酸二乙酯的保留时间为6分钟，林丹的保留时间为12分钟，每15分钟进样一次。对3种典型制剂进行的实验室内部分析表明，变异系数在0.45%至1.58%之间，精密度良好。该方法可轻松适用于林丹的其他液体或粉剂制剂。
