Haohan Chromatography optimized the parameter conditions of the national standard GB 5009.225-2023 for detecting ethanol content. Method: After pre-treatment, the sample was added with tert pentanol standard solution as the internal standard, and chromatographic separation was performed using a quartz capillary column with polyethylene glycol as the stationary phase. Result: Under optimized chromatographic conditions, ethanol showed good correlation within the linear range, with a correlation coefficient of R ≥ 0.995 and a relative standard deviation of less than 2%. The recovery rate of spiked ethanol within the linear range was 99.0%~102.0%, which was better than the method in GB 5009.225-2016. Conclusion: This method is fast, accurate, and suitable for the determination of ethanol content in alcoholic beverages such as fruit wine, wine, and beer.
This standard specifies the method for determining the ethanol concentration (alcohol content) in alcohol and edible alcohol.
The YI method density bottle method is suitable for the determination of ethanol concentration (alcohol content) in alcohol and edible alcohol.
The second method of alcohol measurement is applicable to the determination of ethanol concentration (alcohol content) in alcohol (excluding beer) and edible alcohol.
The third method, gas chromatography, is applicable for the determination of ethanol concentration (alcohol content) in beer, wine, and fruit wine.
The fourth method, the U-shaped oscillating tube digital densitometer method, is suitable for the determination of ethanol concentration (alcohol content) in alcohol and edible alcohol.
