Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses headspace gas chromatography to determine the content of acetaldehyde and acrolein in surface water. The optimized headspace conditions are: equilibrium temperature 80℃, equilibrium time 20 min, and NaCl addition amount 4 g , The sample volume is 10 mL. The minimum detection limits of acetaldehyde and acrolein in water are 0.05 and 0.08 mg/L, respectively. The recovery rate of acetaldehyde is 84.8%～109.1%, acrolein is 79.2%～108.3%; the relative standard deviation of acetaldehyde is 2.4%. ~8.6%, acrolein is 5.2% ~ 10.7%.
