Determination of Crotonaldehyde in Source Water by Gas Chromatography
Determination of Crotonaldehyde in Source Water by Gas Chromatography Details:

Name: Packed Column
Fixative: polyethylene glycol-4000
Carrier: 102 white carrier, 60-80 mesh
Ratio: polyethylene glycol-4000:102 white carrier = 15:100
Specifications: 2m*4mm (inner diameter)
Model: 5%PEG-4000/102
Application: GB 11940-89 Standard method for hygienic inspection of crotonaldehyde in water source water-Gas chromatography

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a headspace gas chromatography (HS-GC) method for the determination of crotonaldehyde in water source water. METHODS: After headspace extraction, trace crotonaldehyde in water was analyzed by GC with a 5% PEG-4000/102 chromatographic column and programmed temperature. RESULTS: The linear range of crotonaldehyde was 6.2~500μg/L, the lowest detection concentration was 4.4μg/L, r=0.9998, the recovery rate of water samples was 95.6%~96.3%, and the RSD was 2.1%~2.9%. Conclusion: The method only takes 2.5 min to complete the determination of crotonaldehyde in drinking water, with simple operation and high sensitivity.
