Although the concentration of fluorinated greenhouse gases such as CFCs, HCFCs, HFCs, and PFCs in the atmosphere is lower than that of CO2, their global warming potential (GWP) is several hundred to tens of thousands of times that of CO2, accounting for 11% of greenhouse gas radiation intensity. They play an important role in global warming and require strengthened control.

In order to better fulfill international conventions such as the Montreal Protocol, the United Nations Framework Convention on Climate Change, and the Kyoto Protocol, and to understand the actual situation in China, the Ministry of Ecology and Environment has required the monitoring of fluorinated greenhouse gases in documents such as the "Carbon Monitoring and Assessment Pilot Work Plan". The monitoring points include various types such as regional background points, urban emission points, and urban background points, with concentration levels distributed in a very wide range of ppt ppm. It has put forward very high requirements for the detection limit, accuracy, and pollution resistance of the analysis system.

To meet the national demand for monitoring and controlling fluorinated greenhouse gases, Beijing Boside Technology, based on years of VOCs monitoring and analysis experience, has launched the BCT 990F high-precision fluorinated greenhouse gas pre concentration system after two years of research and optimization.

Applicable scenarios

The BCT 990F high-precision fluorine-containing greenhouse gas pre concentration system has the advantages of low detection limit, high accuracy, high pollution resistance, and wide detection concentration range, and is suitable for

standard basis

Technical specifications for manual monitoring of ozone depleting substances and fluorinated greenhouse gases in ambient air

Detection Principle

The 990F pre concentrator adopts a dedicated four stage trap design to remove impurities while enriching and concentrating organic halides such as ODS and fluorinated greenhouse gases in the sample. One injection can accurately detect more than 40 substances, with advantages such as low detection limit, high accuracy, strong pollution resistance, and wide detection concentration range.
