Technical highlights

• Multi-component: simultaneous online analysis of multiple gases.
• Universal: including diatomic gases (N2,H2,F2, Cl2, etc.), isotope gases (H2, D2,T2, etc.), and can detect almost all gases except inert gases.
• Rapid response: Complete a single detection within seconds.
• Maintenance-free: can withstand high pressure, direct detection without consumables (chromatographic column, carrier gas).
• Wide quantitative range: detection limit is as low as ppm , and the measurement range can be as high as 100%.


The gas analyzer is based on the principle of laser Raman spectroscopy, can detect all gases except inert gases, and can realize the simultaneous online analysis of multi-component gases.

•   In the petrochemical field, it can detect CH4,C2H6, C3H8, C2H4 and other alkane gases.
•   In the fluorine chemical industry, it can detect corrosive gases such as F2 , BF3 , PF5 , HCl, HF etc.
•   In the metallurgical field, it can detect N2 , H2 ,  O2 ,  CO,  CO, etc.
• It can detect isotope gases such as H2 , D2 , T2 , HD, HT, DT


The gas analyzer adopts the quantitative model of multiple standard curves, combined with the chemometric method, to establish the relationship between the spectral signal (peak intensity or peak area) and the content of multi-component substances. Changes in

sample gas pressure and test conditions do not affect the accuracy of quantitative results, and there is no need to establish a separate quantitative model for each component.
