Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. determined the benzene series in the waste gas of fixed pollution sources according to the linear fitting method in the General Requirements for the Capability of Detection and Calibration Laboratories. Take toluene as the representative material to evaluate the uncertainty. Methods The standard curve of toluene was drawn according to the technical specifications of GB/T22554-2010 (Linear calibration based on standard samples). According to the data of its standard curve, the determination of toluene in waste gas from fixed pollution sources was obtained by statistical method, with an expanded uncertainty of ± 5.524 mg/m3.
The capillary column used in the national standard, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd., has developed a special HH-Benzene series-III benzene series column to replace the capillary column, and the eight components of benzene, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene, cumene and styrene in the waste gas from the fixed pollution source are well separated, with accurate and reliable results.
Specification: 3m * 1/8
Model: HH-Benzene series-III
Application: HJ 1261-2022 Determination of benzene homologues in waste gas from fixed pollution sources Air bag sampling/direct injection - gas chromatography
