High-frequency infrared carbon and sulfur analyzer infrared detection system

The infrared detection pool of the core components is selected from colleges and universities, long-life noble metal miniature infrared light sources and metal mirrors; the modulation system uses a high-precision stepper motor controlled by a single-chip microcomputer to achieve long-term stability of the modulation frequency, combined with infrared heat release at the international advanced level. Electron solid cone sensors, narrowband filters, detectors, etc. The proprietary components and high-accuracy A/D sampling cards of the Shanghai Institute of Technical Physics of the Chinese Academy of Sciences (CAS) enable extremely high detection sensitivity and can effectively detect ppm levels of carbon. Sulfur content.

High-frequency infrared carbon and sulfur analyzer detection range and accuracy

A series of effective measures such as high-pressure ash discharging, pulse back blowing, automatic cleaning, high-precision flow control and pressure compensation are adopted in the design of the gas circuit, and a unique full-scale calibration technique and constant-weight technology for the weight linear compensation gas chamber make the instrument Has a wide range of detection. Detection of up to 99.99% carbon on-line, sulfur up to 99.99%, at the same time choose Germany Germany 10000 electronic balance, the analysis accuracy reached the international advanced level, carbon analysis accuracy ≤ 0.0001% or RSD ≤ 0.5%, sulfur analysis accuracy ≤0.0001% or RSD≤1.0%

High-frequency infrared carbon and sulfur analyzer application software

In the Chinese application software of WindowXP operating system, the PC interface adopts the data exchange technology, constructs a system working mode of communication between the upper and the lower position machines, multi-window, multi-task operation, and realizes the automatic storage and possession of data in the management of the database. Powerful, multi-filtered database search engine, dozens of functions such as synchronous display of working curves, storage, amplification and multiple comparisons of multiple curves. Linearized calibration infrared carbon-sulfur analyzer is used to analyze the carbon and sulfur content of substances by detecting the absorption of infrared radiation by CO2 and SO2 gas; linearization calibration is a key technology in instrument data. Because the Lambert-Beer law is in line with the exponential law, and because the infrared filter has a certain bandwidth, the gas absorption coefficient is not a constant, so it is very difficult to obtain the linear calibration of the integral area. We have made major breakthroughs in the calibration model, calculation method, and calibration software design, and achieved good linearity in the full range.
