A method for the determination of tetramine in postmortem specimens is reported. Tetramine is an organosulfur rodenticide. Parathion, an organophosphorous insecticide, was adopted as the internal standard. Both were extracted from biological materials by benzene and purified by an aluminum oxide column. The extract was analyzed by a gas chromatograph equipped with a nitrogen-phosphorous detector. The extraction efficiency was greater than 90%, and the limit of detection was 0.05 microgram/g for the liver. The standard curve was linear in the range 0.5-50 micrograms/g for the liver, and the correlation coefficient was equal to 0.9993.
本文报道了一种测定死后标本中毒鼠强的方法。毒鼠强是一种有机硫杀鼠剂。采用有机磷杀虫剂对硫磷作为内标。二者均用苯从生物材料中提取，并用氧化铝柱进行纯化。提取物用配备氮磷检测器的气相色谱仪进行分析。提取效率大于90%，肝脏的检测限为0.05微克/克。肝脏中0.5 - 50微克/克范围内标准曲线呈线性，相关系数等于0.9993。
