Five Major Application Categories of Atmospheric Preconcentration Instrument
2026-04-10
The whole software operation interface of the atmospheric pre-concentrator is intuitive, convenient and has good control performance; For atmospheric research, e.g. study of pollution levels, traffic pollution in a global context; It is also used for dynamic monitoring studies to monitor changes in air pollution or trends in biological emissions over a day in urban areas or factory boundaries. The new generation of atmospheric pre-concentrator adopts a new multiple capillary column trapping system, which does not require liquid nitrogen refrigeration or electronic refrigeration, and can be used in connection with any commercially available GC or GCMS to achieve the analysis of volatile organic compounds (VOCs) in air samples.
Application range of atmospheric preconcentrator:
1. Continuous online monitoring of ozone precursors (C2~C10 hydrocarbons) in ambient air or atmosphere;
2. On-line or offline monitoring of odorous compounds such as sulfides, mercaptans and other sulfides, which can reach the level of ppb;
3. Used in USEPA method TO-14(15) to monitor toxic and harmful volatile organic compounds in ambient air;
4. Detect gas purity and odor compounds in industrial production processes;
5. Used for atmospheric research, such as: studying pollution levels and traffic pollution in the global context; It is also used for dynamic monitoring studies to monitor changes in air pollution or trends in biological emissions over a day in urban areas or factory boundaries.
The dilution accessory is used for standard gas dilution and sample gas dilution, using mass flow controller and accurate pressure sensing dual control, standard gas and sample dilution are diluted in two independent channels to avoid cross-contamination; The built-in microprocessor independently controls the operation, which can automatically complete the dilution of various standard gases and samples, and does not need to be connected to an external computer to operate and control, and can automatically calculate the dilution factor.
