Gas analysis instruments are applied in the field of industrial process gas analysis in areas such as chemical engineering, metallurgy, power, and steel production, for monitoring indicators such as gas composition and calorific value. Typical products and technologies include the laser Raman spectroscopy gas analyzer LRGA-6000, in-situ laser process gas analyzer GasTDL-3100, and infrared gas analyzer Gasboard-3500, etc. [1].
In the environmental monitoring field, gas analysis instruments are used for smoke emission monitoring, greenhouse gas flux measurement, and emergency monitoring of sudden pollution incidents. Typical products and technologies include portable gas chromatographs, portable gas analyzers, and continuous emission monitoring systems such as the SERVOPRO 4900 analyzer [1-3] [6].
In the automotive/engine emission testing field, gas analysis instruments are used for actual road driving emission tests that meet standards such as Euro VI RDE, as well as engine research and certification tests. Typical products and technologies include the portable emission testing system Gasboard-9805, engine emission testing system Gasboard-9801, and full-flow dilution volumetric sampling system Gasboard-9802 [1].
In the safety protection field, gas analysis instruments are used in scenarios such as confined space operations, petrochemical inspections, gas maintenance, and fire emergency rescue. Typical products include four-in-one gas detectors that can simultaneously monitor combustible gases, oxygen, hydrogen sulfide, and carbon monoxide, as well as the S4200 electrochemical toxic gas detector [6] [9].
In the research and high-purity analysis field, gas analysis instruments are used for high-precision gas analysis in scientific research, air separation industries, semiconductor manufacturing, and other fields. Typical products and technologies include online process gas chromatographs, Fourier transform infrared spectrometers, trace oxygen analyzers, dew point meters, etc. [1] [4-5] [7].
Gas analysis instruments are also applied in other fields such as gas analysis of packaging container internal atmosphere, food safety testing, and composition analysis of oil and gas.
