Analysis principle

After purification, pure oxygen enters the combustion chamber and is heated by induction heating in a high-frequency furnace. The carbon (C) and sulfur (S) in the sample are converted into CO2 and SO2 under oxygen rich conditions. The generated CO2 and SO2 enter the corresponding optical detection unit for detection after passing through a dust removal and water purification device. The detection signal can be processed to obtain the percentage content of carbon and sulfur elements. The residual gas containing CO2, SO2, and O2 is discharged through a dedicated pipeline after passing through an absorption device.

The core component infrared detection pool adopts the NDIR detection principle that has been tested for decades, with high technological maturity, large range span, and stable operation.

• Selecting efficient and long-life platinum rhodium alloy precious metal micro infrared light sources and metal reflectors for higher optical efficiency;

• Can effectively detect carbon/sulfur content at the ppm level;

• Selecting efficient narrowband infrared filters with good rectangular coefficients, high cut-off depth, high characteristic wavelength transmittance, small bandwidth, and high center wavelength positioning accuracy can better shield the interference of other element spectral lines.

Accurate fluid control technology

• The flow controller adopts a high-precision mass flow meter (MFC) as the main control module, replacing traditional mechanical flow controllers, with more accurate flow control and higher analysis accuracy.

Automatic cleaning and ash discharge design

• Automatic positive pressure pulse dust removal after analysis, improving the stability of raw material analysis and reducing equipment maintenance work;

• Multi stage filtering and dust removal design ensures that the infrared detection chamber is not contaminated and eliminates the trouble of cleaning the chamber for users.

Furnace head constant temperature heating device

• Improve the stability and accuracy of analysis for low content samples and sulfur content.
