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	High-power high-frequency combustion furnace	furnace power of 3.5 kW or more, suitable for steel, alloy steel, ores and other samples; the third-generation furnace head integrates heating, dust back-blowing, dust suction and a cleaning brush; the power is adjusted by the software and saved to the analytical channel, avoiding full-load operation; dual air cooling prevents temperature fluctuation of the infrared cell; intelligent two-zone automatic dust removal combining high-pressure back-blowing, brushing, discharge and collection minimizes dust interference; high-frequency radiation shielding reduces exposure of the operator.
2	High-precision infrared analysis system	infrared thermostat technology improves reproducibility; automatic switching between the high and low measuring cells; intelligent sleep mode; simplified structure with fewer components; a common chopper motor for the carbon and sulfur cells ensures signal consistency; key components are imported.
3	New-generation intelligent analysis software	oscilloscope function for fast circuit diagnosis; multi-stage automatic leak detection and remote online diagnosis and control; automatic shutdown and alarm on operating error or abnormal condition; organic carbon analysis supported.
