白酒中甲醇成分的研究分析毛细管柱
白酒中甲醇成分的研究分析毛细管柱 详细信息：

名称：毛细管柱
规格：60m*0.25mm*0.25um
型号：HH-WAX

浩瀚色谱（山东）应用技术开发有限公司建立白酒中甲醇含量的气相色谱测定方法。方法通过GC法测定白酒中甲醇含量,色谱柱选择HH-WAX石英毛细管色谱柱(60m×0.25mm×0.25μm),程序升温:40℃保持5min,然后以10℃/min的速度升到130℃,保持5min,再以20℃/min的速度升到180℃,保持3min。检测器温度:250℃;进样量:1.0μL。结果甲醇的平均回收率98.3%,RSD1.42%～3.52%,检测限0.02mg/L。结论气相色谱法测定白酒中甲醇含量准确性高,值得推广使用。

Research and Analysis of Methanol Components in Liquor Capillary Column
Research and Analysis of Methanol Components in Liquor Capillary Column Details:

Name: Capillary Column
Specification: 60m*0.25mm*0.25um
Model: HH-WAX

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. established a gas chromatography method for the determination of methanol content in liquor. Methods The methanol content in liquor was determined by GC method. The chromatographic column was HH-WAX quartz capillary column (60m×0.25mm×0.25μm), and the temperature was programmed: 40℃ for 5min, then 10℃/min to 130℃ , Keep it for 5min, then increase to 180℃ at a rate of 20℃/min, keep it for 3min. Detector temperature: 250°C; injection volume: 1.0μL. Results The average recovery rate of methanol was 98.3%, the RSD was 1.42%～3.52%, and the detection limit was 0.02mg/L. Conclusion The determination of methanol content in liquor by gas chromatography is highly accurate, and it is worthy of popularization.
