Method basis
According to the Gas Chromatography Method HJ/T 35-1999 for the Determination of Acetaldehyde in Exhaust Gas from Fixed Pollution Sources.
2. Method principle
Sampling with sodium bisulfite solution, acetaldehyde undergoes nucleophilic addition reaction with sodium bisulfite to generate stable alpha hydroxysulfonate in neutral solution. Then, acetaldehyde is released by co heating in dilute alkaline solution, separated by chromatographic column, and determined by hydrogen flame ionization detector. The retention time of the standard sample chromatographic peak is qualitative, and the peak height is quantitative.

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 ｦﾌ l, the detection limit of acetaldehyde is 4 ｡ﾁ 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 Shimadzu chromatography column for the determination of acetaldehyde in exhaust gas from fixed pollution sources. The column has high column efficiency, good separation, no interference from methanol, ethanol, and acetone, good separation, symmetrical peak shapes, and satisfactory results.
