For foundry companies, the front of the furnace is a crucial link. Spark photoelectric optical emission spectrometers are increasingly used by foundry companies to detect samples before furnaces to control the quality of products. Therefore, it is very important for laboratories to choose a good spark photoelectric optical emission spectrometer.
Innovate T5 spark photoelectric optical emission spectrometer adopts the international leading CMOS detector. So what are the advantages compared with the traditional CCD detector?
First of all, CMOS detector not only has the full-spectrum detection characteristics of CCD, but also has the advantage of extremely low detection limit of PMT. The birth of CMOS detector solves the limitation of the number of PMT channels and the defect that CCD cannot detect high-purity metal.
Secondly, for elements with ultraviolet wavelengths below 200nm such as carbon, sulfur, and phosphorus, CCD need to be coated with organic films for detection. The organic films will deteriorate after two years of use which causing signal attenuation and resulting in a decrease in the detection accuracy of ultraviolet wavelength elements. However, CMOS detectors can directly detect ultraviolet wavelength elements without coating. It's much longer service life and better detection accuracy.
In summary, CMOS full-spectrum spark photoelectric optical emission spectrometer is the best choice for the inspection before furnace.
