Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a gas chromatography method for the determination of acetaldehyde in environmental atmosphere. The sampling efficiency is above 995, the recovery rate is 92.8% -99.5%, and the coefficient of variation is 2.56% -3.24%. When the sampling volume is 10L, the minimum detectable concentration is 0.14mg/m ^ 3.
HJ/T 35-1999
This standard is applicable to the determination of acetaldehyde in organized and unorganized emissions from fixed pollution sources. When the sampling condition is 100L and the injection condition is 1 μ l, the detection limit of acetaldehyde is 4 × 10-2mg/m3, and the quantitative determination concentration range of acetaldehyde is 0.14mg/m3 to 30mg/m3.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a PEG-20M/GCS880 AW DMCS packed chromatography column based on national standards. The column has high column efficiency, good separation, and does not interfere with methanol, propylene glycol, ethanol, vinyl chloride, etc. It has high efficiency and short analysis time for the determination of acetaldehyde in waste gas from fixed pollution sources.
