| 摘 要： | 本文建立了海参口服液中甲基汞含量的毛细管气相色谱测定方法。该法采用WBI进样口，毛细管色谱柱DB-5（弱极性，30m×0．53mm×0．5μm），ECD检测器进行检测。进样口温度：200~C，载气流速：10mL／min，柱室温度：100℃保持2min，以5℃／min升至230℃．检测器温度：300℃。方法简单、快速、重现性好，平均回收率大于85％，RSD小于3．0％，线性范围为0．1μg／mL-1．0μg／mL。

| Abstract: | The method is established for the determination of Methylmercury in Sea Cucumber Oral Liquid by Capillary GC. The separation was achieved by using WBI injection port, Capillary GC column DB-5（weak polarity,30m ×0.53 mm × 0.5 μm）, ECD detector. Injecton port temperature： 200℃, flow of carrier gas：10 mL/min, column oven temperature： 100℃ keep 2 min, then 5℃/min up to 230℃, detector temperature： 300℃. The method is accurate, rapid and convenient. The results indicate that the recovery is more than 85%, RSD is less than 3.0% and the working curve of Methylmercury is in the linear range 0.1 μ g/mL- 1.0 μ g/mL. |
