Determination of Acetaldehyde in Ambient Air by Packed Column Gas Chromatography
Determination of Acetaldehyde in Ambient Air by Packed Column Gas Chromatography Details:

Name: Packed Column
Specifications: 2m*3mm (inner diameter)
Model: 20%PEG-20M/GCS880 AW DMCS (80-100 mesh)

Application: HJ/T 35-1999 Determination of Acetaldehyde in Exhaust Gas from Stationary Pollution Source Gas Chromatography

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a gas chromatography method for the determination of acetaldehyde in ambient atmosphere. The sampling efficiency was above 99%, the recovery rate was 92.8%-99.5%, and the coefficient of variation was 2.56%-3.24%. When the sampling volume was 10L, the minimum detectable concentration was 0.14mg/m3.
