A method was developed to measure the tetramine in plasma by liquid-liquid extraction and GC-NPD with the limit of detection (LOD) 1.5 pg and the limit of quantity 10 ng/ml. The linear range was 0.1-5 micrograms/ml with a correlation coefficient of 0.999. Recoveries for three concentrations of tetramine were 96.0%, 107.0%, 106.8%. The intra-day precision were 9.6%, 9.8%, 7.8%, the inter-day precision were 6.6%, 8.5%, 6.2%. Tetramine in plasma was stable up to 5 months at -4 degrees C.
建立了一种通过液-液萃取和气相色谱-氮磷检测器测定血浆中毒鼠强的方法，检测限为1.5 pg，定量限为10 ng/ml。线性范围为0.1-5 μg/ml，相关系数为0.999。三种浓度毒鼠强的回收率分别为96.0%、107.0%、106.8%。日内精密度分别为9.6%、9.8%、7.8%，日间精密度分别为6.6%、8.5%、6.2%。血浆中的毒鼠强在-4℃下可稳定保存5个月。
