HJ/T 35-1999 Determination of acetaldehyde in exhaust gas from stationary pollution sources-Gas chromatography

1.1 This standard applies to the determination of acetaldehyde in organized and unorganized emissions from stationary sources.

1.2 When the sampling volume is 100L and the injection volume is 1μL, the detection limit of acetaldehyde is 4×10-2mg/m3, and the quantitative determination concentration range of acetaldehyde is 0.14mg/m3-30mg/m3.

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. uses gas chromatography to determine acetaldehyde in ambient air and industrial waste gas. 1% NaHSO_3 solution was used for enrichment and absorption, PEG-20M was used as fixed solution, GCS-880-AW-DMCS was used as carrier, and the chromatographic determination was carried out with hydrogen flame ionization detector. Sampling methods, sample preservation and optimal chromatographic conditions were studied. The sampling efficiency of the method is not less than 99.0%; the precision and accuracy are high; the minimum detection concentration of the method is 0.04 mg/m^3.
