顶空毛细管气相色谱法测定曲克芦丁中环氧乙烷残留量

Determination of residual ethylene oxide in troxerutin by headspace capillary gas chromatography.

建立了顶空毛细管气相色谱法测定曲克芦丁中环氧乙烷残留量的方法。环氧乙烷浓度在0.1～3.0μg/mL范围内,线性与精密度良好,平均回收率为100.6%,最低检出限为0.04μg/mL,线性方程为Y=10247.99c -539.76,相关系数为0.999。方法简便,结果准确。

The ethylene oxide residue in troxerutin was determined by headspace capillary gas chromatography. The linearity and precision were good in the range of 0. l-3.0μg/mL with the lowest detection limit of 0.04 μg/mL and the average recovery was 100.6%. The linear equation is y ： 10247.99c - 539.76 （r = 0. 999） . The method is simple and the results are accurate.
