The S7060 Gas Chromatograph is an analyzer dedicated to the detection of non-methane total hydrocarbons (NMHC) and benzene series. In addition to the standard separation and measurement systems inherent in conventional chromatographs, it is equipped with flexible touch-screen operation software and versatile measurement functions. Adopting the high-temperature heat tracing dual-column parallel backflush chromatographic separation technology, the instrument can automatically measure and analyze the contents of methane, total hydrocarbons and benzene series. The content of non-methane total hydrocarbons is derived from the difference between the total hydrocarbon content and the methane content, which significantly shortens the analysis cycle. Typical application fields include coating manufacturing, organic chemical industry, wire and cable manufacturing, tire manufacturing, petroleum cracking, semiconductor integrated manufacturing, garment manufacturing, pharmaceutical production, packaging and printing, etc.

The S3000 Thermal Conductivity Analyzer determines gas components based on the differences in thermal conductivity of gases. Specifically, it measures the thermal conductivity of a mixed gas to determine the content of a specific gas within it. Hydrogen in the mixed gas has a high thermal conductivity, 7–8 times higher than that of nitrogen, oxygen, and other gases. Therefore, when the background gas or other components in the mixture remain basically constant, the thermal conductivity of the mixed gas depends essentially on the hydrogen content. Based on this principle, the analyzer can accurately measure the hydrogen concentration by detecting the thermal conductivity of the mixed gas. It is suitable for continuous and automatic analysis of hydrogen percentage concentration in various mixed gases, and can be widely used in industries such as petrochemicals, metallurgy, electric power, biological fermentation, and air separation.

The S2000 Infrared Gas Analyzer is an analytical instrument developed for international environmental protection, carbon emission control, and industrial process analysis It is primarily based on Gas Filter Correlation (GFC) technology and Non-Dispersive Infrared Absorption (NDIR) method, combined with independently designed long-path gas cells (L-Cell), wavelength filters, infrared detectors, and high-precision signal processing circuits This configuration enables quantitative analysis of gases in the infrared band The analyzer is capable of measuring the concentrations of various gases including CO2, CH4, CO, N2O, O2, and others。

The Model S1000 Oxygen Analyzer adopts multi-principle sensors including paramagnetic oxygen, ion current and electrochemical sensors. It features fast response time and long service life, and can meet the analysis and detection requirements of percentage content, trace and high-purity levels simultaneously. For different gas environments, the instrument applies sensors with different technical principles. Combined with the ARM embedded system, it can be used for real-time measurement and analysis of oxygen concentration in various measuring environments such as pure gas, inert gas and special atmosphere (acidic and alkaline environments). Integrated with flow control, temperature compensation and pressure control systems, the instrument is equipped with a user-friendly operation platform and boasts wide usability.
