Determination of benzene series of air pollutants in the pharmaceutical industry
Determination of benzene series of air pollutants in the pharmaceutical industry Details:

Name: Adsorption tube

Specification: 1/4*3.5
Filler: 200mg
Shape: U, straight pipe

Model: TENAX-TA

Application: Air Pollutant Emission Standard for the Pharmaceutical Industry (GB 37823—2019)

Volatile organic compounds (VOCs) are organic compounds that participate in atmospheric photochemical reactions, or organic compounds determined in accordance with relevant regulations. When characterizing the overall emissions of VOCs, according to industry characteristics and environmental management requirements, total volatile organic compounds (expressed in TVOC) and non-methane total hydrocarbons (expressed in NMHC) can be used as pollutant control items.

3.12 Total volatile organic compounds (TVOC) adopts the prescribed monitoring method to measure the individual VOCs in the exhaust gas, and add the total amount of VOCs to obtain the total mass concentration of the individual VOCs. In actual work, the individual VOCs that account for more than 90% of the total should be measured and summed according to the expected analysis results.

3.13 Non-methane hydrocarbons (NMHC) adopt the prescribed monitoring method. The sum of gaseous organic compounds other than methane to which the hydrogen flame ionization detector responds is measured by the mass concentration of carbon.

3.14 Process vents Waste gas discharged from the pharmaceutical production process, including process exhausts such as preparation, synthesis, extraction, crystallization, centrifugation, filtration, drying, refining, packaging, solvent recovery, and auxiliary equipment such as vacuum pumps.

3.15 tail gas from fermentation The waste gas containing biological metabolites discharged from the microbial fermentation tank during the production process of fermentation chemical raw materials also includes the pollutant-containing steam discharged from the fermentation tank during the cleaning and disinfection process.

3.16 fugitive emission The random emission of air pollutants without passing through the exhaust tube, including the escape of open workplaces, and the emission through gaps, vents, open doors and windows, and similar openings (holes).


Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used gas chromatography and TENAX-TA adsorption tube enrichment to successfully determine the residual benzene series of air pollutants in the pharmaceutical industry. The column efficiency is high, the separation is good, and the results are satisfactory.
