Packed column for determination of acetaldehyde and acrolein in water source water
  Packed column for determination of acetaldehyde and acrolein in source water Details:

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. has studied the purge and trap-gas chromatography method for the determination of acetaldehyde and acrolein in drinking water source water, and optimized the purge and trap measurement conditions and studied the purge The effect of time and temperature on the experimental results. Experiments show that when the purge temperature is 30℃ and the purge time is 15min, satisfactory experimental results can be obtained. The detection limit of acetaldehyde is 0.0010mg/L, and the detection limit of acrolein is 0.0010mg/L. The detection limit is 0.0007mg/L.
