　　Haohan Chromatography has established a gas chromatography method for the determination of acetaldehyde and acrolein in water. Standard addition recovery tests were conducted at three different concentration levels: high, medium, and low. The recovery rate can reach 94.2-103.6%, and the relative standard deviation is 0.7-7.1%. This method is accurate, effective, and highly sensitive, and is suitable for the determination of trace amounts of acetaldehyde and acrolein in water

　　This standard specifies the use of gas chromatography to determine acetaldehyde and acrolein in source water.

　　This standard is applicable for the determination of acetaldehyde and acrolein in source water. If injected directly, the low detection concentration of acetaldehyde in this method is 24mg/L, with acrolein at 0.019 mg/L. If distillation concentration is carried out, the low detection concentration can also be reduced.
