How to choose infrared carbon and sulfur analyzer to determine carbon and sulfur requirements in steel
Nanjing Qilin Scientific Instrument Group Testing Center recommends that when selecting suitable laboratory equipment, the foundry first understands the range of element content of the test object, and selects the most suitable instrument for the company according to the content range. If the accuracy of the experimental results is high, then the appropriate test equipment should be selected according to the element range of the test materials, such as: cast iron, plain carbon steel, alloy steel can choose ordinary gas volume method carbon sulfur meter, and stainless steel" Target=_blank>Infrared carbon and sulfur analyzers are required for stainless steel, high chromium cast iron, non-ferrous metals, etc.
Many factory laboratories often use the method of contact measurement when measuring carbon and sulfur in steel, that is, the sample is subjected to high temperature combustion to produce carbon dioxide and sulfur dioxide, which is first absorbed by the starch solution (or absorbed by H2O2 solution), and the sulfur is titrated by iodometric method. Or acid-base titration), and then introduce residual gas into the carbon analyzer for carbon determination. It should be noted that when the mixed gas passes through the starch solution (neutral or acidic), a small amount of carbon dioxide is absorbed (through the H2O2 solution). The same is true, resulting in a low carbon measurement result.
The QL-HW2000B high frequency infrared carbon and sulfur analyzer produced by Nanjing Kirin is a collecting light. High-tech products integrating machine, electricity, computer and analytical technology can accurately detect carbon and sulfur in ferroalloy and stainless steel "target=_blank> stainless steel, carbon steel, alloy steel, cast iron, ductile iron, non-ferrous metals and other materials. It has the characteristics of wide measuring range, strong anti-interference ability, complete functions, simple operation, fast and accurate analysis results, and has been well received by thousands of customers since it was put into the market with reasonable price, accurate detection and intimate after-sales service. !
