Abstract

The invention discloses an adjustable chopped infrared carbon-sulfur analyzer used for analyzing the contents of carbon and sulfur in a sample. The adjustable chopped infrared carbon-sulfur analyzer comprises an electronic scale, an oxygen source, a combustion furnace, an adjustable chopped infrared detection device and a control host, wherein the adjustable chopped infrared detection device comprises an infrared light source module for generating an infrared measurement light source with adjustable chopping frequency, a chopper, a carbon-sulfur absorption pool used for detecting the carbon-sulfur contents in a mixed gas generated after the sample is burned in the combustion furnace, an optical filter, an infrared detector, a front plate and an analog switch; and the chopper is provided with a chopping motor and the like. The adjustable chopped infrared carbon-sulfur analyzer has the advantages of high computation speed, strong anti-jamming capability, high analysis result precision, optimized structure, high cost performance and the like.

Description

Technical field [0001] The invention relates to the technical field of material carbon and sulfur content analysis, in particular to an adjustable chopping infrared carbon and sulfur analyzer with convenient operation, fast analysis speed and more accurate detection results. Background technique [0002] At present, most users in domestic metallurgy, foundry, machinery, chemical and other industries mainly use infrared photometry (infrared carbon and sulfur analyzer) and gas volume method plus iodometry (high-speed carbon and sulfur analysis) when analyzing carbon and sulfur elements in materials. instrument). Due to the relatively high precision, rapid and convenient infrared photometric method for detecting carbon and sulfur, the demand for infrared carbon and sulfur analyzers is increasing, but the price of infrared carbon and sulfur analyzers is higher, which affects the promotion of small and medium-sized enterprises. [0003] The utility model patents with patent application...
