Determination of ethanol concentration in alcohol and edible alcohol using polyethylene glycol capillary column
Determination of ethanol concentration in alcohol and edible alcohol - Detailed information on polyethylene glycol capillary columns:
Name: Capillary Column
Fixed phase: Healthy/cross-linked polyethylene glycol
Model: PEG-20M
Specification: 60m * 0.25mm * 0.25um
*High temperature: 250 ° C
Application: GB 5009.225-2023 National Food Safety Standard - Determination of Ethanol Concentration in Liquor and Edible Alcohol
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.
Haohan Chromatography has established a gas chromatography method for determining the ethanol concentration of wine, fruit wine, and beer using n-propanol as the internal standard. The results showed that the ethanol concentration was between 0.10% and 2.00%, and the linear relationship of the method was good. The correlation coefficient r was greater than 0.9999, the RSD was between 0.196% and 0.648%, and the spiked recovery rate was between 98.2% and 100.0%. The t-test values in the method comparison were between 0.60 and 1.52. This method has high accuracy and good precision, and is suitable for detecting ethanol concentration in wine, fruit wine, and beer.
