Simultaneous determination of acetaldehyde and acrolein in water by gas chromatography

Name: Spiral stainless steel column
Stationary phase: use 20% polyethylene glycol 20M as the stationary liquid, and coat it on the 6201 glazed support (60^80 mesh)
Specification: 2m*4mm (inner diameter)
Application: GB 11934-1989 Standard method for hygienic inspection of acetaldehyde and propionaldehyde in source water gas chromatography





Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. is a method for simultaneous determination of acetaldehyde and acrolein in drinking water source water. Method  Using simple, fast and sensitive gas chromatography. Results  The lowest detection limit of acetaldehyde was 0.2ng, acrolein was 0.452ng, the precision of acetaldehyde and acrolein was 415%～546%; the recovery rate was 94%～1024%. Conclusion  This method can meet the requirements of drinking water hygiene standards,
