Embodiment Construction
[0014] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0015] Such as figure 1 As shown, the infrared carbon determination and sulfur determination analyzer includes an oxidation unit, an infrared absorption unit, a gas path control unit and a detection unit. Wherein the oxidation unit comprises a combustion furnace 10 heated by a high-frequency power supply 9 and an oxygen source 1, the oxygen source 1 is connected to the combustion furnace 10 through a mass flow controller 3 and a drive cylinder 5, and the solenoid valve 2 is connected to the mass flow controller 3 connections control the flow and quality of oxygen entering the burner 10. The electromagnetic valve 4 is connected with the driving cylinder 5 to control the on-off of the air inlet and the air outlet of the combustion furnace 10 .
[0016] The infrared absorption unit includes an infrared light source 8 and an absorption pool...

Abstract
The invention discloses an infrared carbon and sulfur determination analyzer, which comprises an oxidation unit, an infrared absorption unit and a detection unit. The oxidation unit comprises a combustion furnace and an oxygen source, and the combustion furnace is connected with the oxygen source; the infrared absorption unit comprises an absorption cell and an infrared light source, wherein the infrared ray generated by the infrared light source passes through the absorption cell, and the absorption cell is connected with the air outlet of the combustion furnace; and the detection unit comprises a detector and a master control board for analyzing the content of carbon and sulfur, wherein the detector can receive the infrared ray passing through the absorption cell and is connected with the master control board. The analyzer has simple structure and convenient operation, and can very accurately measure the content of carbon and sulfur in a substance.
Description
technical field [0001] The invention relates to an analyzer for determining carbon and sulfur, in particular to an analyzer for analyzing the carbon and sulfur contents in substances by means of infrared rays. Background technique [0002] Carbon determination and sulfur determination analyzer is a commonly used analytical instrument for analyzing carbon and sulfur content in substances, and can quickly analyze steel, cast iron, copper, alloy, ore, cement, ceramics, carbon compounds, minerals, coal, coke , petroleum, ash, catalyst, lime, gypsum, soil, rubber, leaves, soot, garbage, sand, glass and other solid and fluid materials, are widely used in scientific research, production and processing, etc. field. [0003] The principle of the commonly used carbon and sulfur determination analyzer is mainly to heat and melt the solid powder sample to be tested in an environment of pure oxygen, so that the carbon and sulfur in the sample will react with oxygen, so that carbon, Sul...
