Determination of Benzenes in Air Pollutant Emissions from TACEF Auto Repair Industry HH-INNOWAX Capillary Column
HH-INNOWAX capillary column for the determination of benzene series of air pollutants emitted by TACEF auto repair industry Details:
Name: capillary column
Stationary Phase: Polyethylene Glycol
Specifications: 30m*0.53mm*1.0um
Model: HH-Innowax
Application: stationary pollution source waste gas, determination of benzene series, air bag sampling, direct sampling - gas chromatography
"Automobile Maintenance Industry Air Pollutant Emission Standard" (DB31 1288-2021)
The components in the exhaust gas emitted by the automobile manufacturing industry are relatively complex. During the gas chromatography analysis process, chromatographic peaks overlap, and the chromatographic peaks of each substance cannot be effectively separated, thus affecting the accurate quantification of the test. The interference ZUI of the benzene test is: severe. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. optimizes the existing gas chromatograph conditions by using GC-FID of medium and strong polar chromatographic columns and adopts GC-MS method to determine benzene. After the optimization of the method, the linear correlation coefficient was greater than 0.999, the recovery rate of standard addition was 80%-83%, and the precision was 2.48%-3.80% (n=7). The optimized method can meet the analysis requirements of benzene series in exhaust gas of automobile industry.
