摘要
本文报导了用PE2400元素分析仪进行低含量C,H,N测定时宜采用的方法步骤.用该法测定了含量在0.5%以下样品.回收率在95%-105%之间,标准偏差≤0.006%.
A modification is reported for determination of C, H, N in organic compounds using a PE2400 C, H, N Elemental Analyzer. The recovery rate is 90%~105% and standard deviation is≤0. 006% when the level of C, H and N is lower than 0.5%.
