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.
