Online MS
The GSD100 Online Mass Spectrometer adopts a high-performance quadrupole mass analyzer, together with dedicated software and sampling system designed for process gas analysis. It enables real-time, online rapid multi-component analysis of process gases. Beyond the powerful functions of conventional online mass spectrometers, this instrument features compact size and fast response, suitable for on-site detection. It supports qualitative and quantitative online analysis of gas species, and is widely applied in chemical industry, catalysis, geological analysis, environmental fermentation, iron and steel metallurgy, semiconductors, isotope analysis, glass bubble analysis, gas calibration, automotive exhaust analysis, flue gas analysis and other fields.
Product Advantages
On-site detection & online analysis: Simultaneous on-site monitoring of multiple components, enabling rapid analysis for emergency events.
High degree of automation: Dynamic and continuous sampling for online gas analysis; fast response and powerful data analysis capability.
Customizable on demand: Sampling and pre-treatment units can be configured to realize pressure regulation, filtration, dehumidification, heating and other functions.
Temperature-controlled inlet pipeline: Effectively prevents condensation of process gas during sampling. Dual filaments with high integration: Equipped with two-stage vacuum pumps, covering applications from high pressure to ultra-high vacuum.
High efficiency and wide measurement range: Warm-up time is only 3 minutes; capillary sampling takes less than 2 seconds; full-spectrum scan over 1–100/200/300 amu takes less than 1 second. It can measure concentrations ranging from PPb to 100%.
Customized service and turnkey total solutions are available for different applications. The sample gas conditioning system, sampling interface, vacuum system, software and database of the online mass spectrometer can be specially configured and designed according to user requirements.
