This document describes the application of Agilent J&W FactorFour VF-WAXms GC Columns in beer analysis.
The document provides a specific analytical method for detecting volatile compounds in beer. The technique utilizes Gas Chromatography with Flame Ionization Detection (GC-FID) to identify various alcohols, esters, and other volatiles present in the sample.
The procedure specifies the use of an Agilent J&W FactorFour VF-WAXms column (part number CP9211). The method includes detailed operating conditions for the injector, detector, carrier gas flow, and a temperature program ranging from 55 °C to 220 °C.
| Carrier Gas | Helium, 0.7 bar |
|---|---|
| Injector Temperature | 250 °C |
| Split Ratio Flow | 30 mL/min |
| Detector Temperature | 275 °C |
| Column Part Number | CP9211 |
The method identifies acetaldehyde, dimethyl sulfide, acetone, ethyl formate, ethyl acetate, ethanol, isobutanol, isoamyl acetate, and 3-methyl-1-butanol.
The oven starts at 55 °C held for 2 minutes, then ramps to 220 °C.
