Haohan Chromatography uses gas chromatography to determine the ethanol content in alcoholic beverages: the internal standard is tert pentanol Injection port and detector temperature: 250 ℃; Carrier gas flow rate: 1.0mL/min; Purging flow rate: 3.0mL/min; Split ratio: 1:99; Tail blowing flow rate: 30mL/min; Hydrogen flow rate: 40mL/min; Air flow rate: 400mL/min. Shortened sample processing time and improved measurement accuracy.
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.
