Capillary Column Determination of Methanol in Food
Capillary Column Determination of Methanol in Food Details:

Name: Capillary Column
Specification: 60m*0.25mm*0.25um
Model: PEG-20M
Application: GB 5009.266-2016 National Food Safety Standard Determination of Methanol in Food

This standard replaces GB/T 5009.48-2003 Method for the determination of methanol in the hygienic standards of distilled and mixed liquors on June 23, 2017, the method for determination of methanol in GB/T 15038-2006 General analytical methods for wine and fruit wine, and GB/T 15038-2006 /T 394.2-2008 Determination of methanol in general analytical methods for alcohol.
This method specifies the determination method of methanol in alcohol, distilled wine, mixed wine and fermented wine.
This method is suitable for the determination of methanol in alcohol, distilled wine, mixed wine and fermented wine.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has established an analytical method for the determination of methanol in wine by headspace-gas chromatography. A hydrogen flame ionization detector was used, HH-wax type capillary chromatographic column was selected as the separation column, the temperature was programmed, the carrier gas nitrogen flow rate was 1.5m L/min, and the split ratio was 3:1. For the headspace sampler, the heating temperature of the headspace bottle is 65℃, and the equilibration time is 25min. The results show that the mass concentration of methanol measured by this method has a good linear relationship with the peak area in the range of 59.9~359.4mg/L, and the correlation coefficient is 0.9995. The sample recovery rate was 95.0%-99.2%, and the minimum detection limit was 0.005g/L. This method is fast, simple, accurate and sensitive, and is suitable for the detection of methanol mass concentration in wine.
