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	high-power design suitable for the combustion of many kinds of samples including steel, alloy steel and ores; the third-generation furnace head integrates heating and dust cleaning, improving functionality and integration; the power is automatically adjusted to the sample, which meets the combustion requirement without running at full load and extends the service life; dual air cooling effectively cools the furnace and prevents overheating from affecting accuracy.
2	High-precision infrared analysis system	constant-temperature control reduces the influence of ambient temperature changes; high/low measuring cells switch automatically without manual intervention; intelligent sleep mode reduces fire risk and extends the service life; the optimized design simplifies the structure and reduces the number of components; the carbon and sulfur cells share one chopper motor, ensuring pulse signal consistency and reducing background interference.
3	New-generation intelligent analysis software	an oscilloscope function allows fast diagnosis of circuit problems; automatic leak checking and remote online diagnosis; the instrument stops automatically and raises an alarm in case of operating error or abnormal condition; organic carbon analysis is supported in addition to routine analysis.
