中文摘要: |
采用毛细管气相色谱内标法测定羟乙基乙二胺中的乙二胺含量.结果表明,乙二胺在0.1~2.0 mg/mL范围内的线性关系良好(r=0.9997),检出限为0.02 mg/mL,方法的精密度RSD为1.7%(n=6),加标回收率在95%~101%. |
英文摘要: |
Ethylenediamine in 2-(2- Aminoethylamino) ethanol was determined by capillary gas chromatography with internal standard method. The results showed that calibration curves presented good linear relationship in the range of 0.1~2.0 mg/mL with a correlation coefficient of 0.9997. The detection limit of the method was 0.02 mg/mL.The relative standard deviation (RSD)of the method was 1.7%(n=6).The recovery achieved 95%~101%. |
