GB 11934-1989 Hygienic inspection standard method for acetaldehyde and acrolein in source water - Gas chromatography method
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 minimum detectable concentration of acetaldehyde in this method is 24mg/L, with acrolein at 0.019 mg/L. If distillation concentration is carried out, the minimum detectable concentration can be further reduced.
