Capillary Column for Determination of Air Pollutant TVOC in Pharmaceutical Industry
TVOC capillary column for determination of air pollutants in the pharmaceutical industry Details:

Name: Capillary Column
Specification: 50m*0.32mm*1.0um
Model: HH-1
Application: Emission Standard of Air Pollutants for the Pharmaceutical Industry (GB 37823—2019)


Strengthening the requirements for unorganized emission control is a major feature of this standard. The standard divides fugitive emissions into five processes, one is the unorganized emission source of the process, and the fourth is the unorganized emission source of general facilities (VOCs material storage control requirements, VOCs material transfer and transportation control requirements, equipment and pipeline leakage and open (VOCs on the liquid level escape). Among them, VOCs material transfer and transportation control requirements, equipment and pipeline leakage unorganized emission requirements refer to the "Volatile Organic Compounds Unorganized Emission Control Standard" (GB37822-2019) issued simultaneously with the standard.

The control requirements for fugitive emissions in the process are mainly to strengthen the sealing of equipment and control measures that are likely to cause VOCs to escape. VOCs material storage is mainly to control the discharge of storage tanks. The scale of storage tanks of pharmaceutical companies is relatively small, so the control scale limit is relatively lower. There are also open liquid level VOCs that escape, because most pharmaceutical companies need to consider deodorization and other reasons, so measures such as capping and sealing are required. The unorganized emission of VOCs requires zoning management, and higher levels of unorganized emission control are required for pharmaceutical companies located in key areas.

 For the management and control of unorganized emissions in the plant area, this standard has increased the unorganized emission limit of VOCs, and the local ecological environment authority can determine the specific implementation method by itself according to the local environmental protection needs. According to the results of the current investigation, if the internal control of the workshop is good, there will not be too much pressure to meet the requirements.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd., using HH-1 capillary column to determine the air pollutant TVOC in the pharmaceutical industry---benzene, toluene, para, meta, p-xylene, styrene, n-butyl acetate, n-eleven The alkane separation was good and the results were satisfactory.
