How to quickly determine ethanol content
The ethanol content can be determined quickly using a gas chromatograph
Using a thermal conductivity detector and GDX-104 stationary phase, the analysis takes only 5 minutes per run
The testing standard for ethanol is chromatographic analysis
Vapor phase can only be used to determine organic impurities; I wonder if a graphical method can be developed for this purpose
Gas chromatography detection conditions: Hydrogen flame ionization detector, GDX-102 column; vaporization chamber temperature 190°C, detector temperature 190°C, column temperature 170°C
Using an alcohol meter is fast, but the measurement results are not precise enough. Using a densimeter for conversion is more accurate, but it is slower.
If high precision in the results is not required, using an alcohol meter is fast. If high precision in the results is required, gas chromatography can be used; the speed is also acceptable.
