Determination of Benzene and Benzene in Indoor Air by Gas Chromatography
Determination of Benzene and Benzene in Indoor Air by Gas Chromatography

Stationary phase: dedicated

Specification: 2m*1/8

Particle size: 60-80 mesh
Model: HH-JIABEN

Application: Determination of benzene series


Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. uses gas chromatography to determine benzene and benzene in indoor air. Methods: The collection of activated carbon tube, carbon disulfide analysis, toluene column as separation column, FID detector, the linearity and calculation factor of benzene and benzene series were investigated. Results: based on the peak area, the linear regression was good and can be accurately quantified. The calculation factors of benzene, toluene, ethylbenzene, m-p-xylene and o-xylene were 6.266×10-4 and 6.527×10, respectively. -4, 6.647×10-4, 5.599×10-4, 7.120×10-4. The student dormitory, canteen, restaurant, and supermarket were measured. The results showed that the benzene concentration in the above sites was less than 0.09 mg/m3, and the total concentration of benzene compounds was less than 0.9 mg/m3.
