I. Working Principle

The high-frequency infrared carbon-sulfur analyzer is a modern analytical instrument developed on the principle that CO₂ and SO₂ selectively absorb infrared radiation. It consists of an automatic constant-pressure oxygen supply, high-frequency induction heating, infrared detection, a microcomputer, a printer and an electronic balance. When the sample burns in the high-frequency furnace, the CO₂ and SO₂ generated are carried by oxygen into the infrared detector; the signal is pre-amplified and processed by the computer, and the carbon and sulfur percentages are displayed on the colour monitor and printed out.

II. Product Features

1	Full stainless steel gas path	all plastic tubing has been replaced by stainless steel tubing, making the gas path compact, easy to troubleshoot and more corrosion resistant; the lower specific surface area reduces adsorption and improves precision for low-content samples.
2	Vacuum ceramic capacitor	higher-frequency power release and better long-term stability.
3	Preheating function	the high-frequency generator starts before the oxygen is admitted, which solves the sample-blowing problem caused by the large top oxygen demand of low-density, hard-to-burn samples.
4	Double-layer infrared cell isolation	minimizes the effect of ambient temperature changes on long-term stability.
5	Third-generation furnace head	integrates internal heating, dust back-blowing, dust suction and a cleaning brush.
6	Hollow furnace tail	leaves no hiding place for dust, eliminates blind zones during dust suction and conveys dust directly from the furnace head to the dust collection box.
7	Patented cleaning brush	instead of the conventional edge air intake, oxygen passes through a large central channel.
8	Automatic quartz combustion tube loading	an internationally leading feature comparable to top European and American products.
9	Improved natural convection cooling	the electronic tube stays below 80 °C during continuous operation, which slows down ageing and greatly extends the service life.
10	Automatic sample feeding system (optional)	automatically judges the reliability of the test data.
11	Whole-machine condition monitoring	current, voltage, gas flow and gas pressure are monitored continuously, with an alarm when the temperature is overloaded.
