High pressure ash removal, automatic cleaning, and high precision are adopted in the design of the gas pathflow controlA series of effective measures such as pressure compensation, combined with DeKai Company's comprehensiverangeCalibration technology and weight linear compensation technology enable the instrument to have a wide detection range. The detection limit can reach 100% carbon and 100% sulfur, and Mettler from Switzerland is also selected-Toledoone in ten thousandelectronic balanceMake the analysis accuracy reach * level, carbon analysis accuracy ≤ 0.4ppm orRSD≤ 0.4%, sulfur analysis accuracy ≤ 0.5ppm or RSD ≤ 1.2%.

Linearization calibration

Infrared carbon sulfur analyzerIt's through testingCO2And SO2 gas on infraredradiationAnalyze the carbon and sulfur content in a substance based on its absorption capacity; Linearization calibration is a technique used in instrument datakey technologyDue toLambertBill's law follows an exponential law, and because infrared filters have a certain bandwidth, gasesabsorption coefficientIt is not a constant, so it is very difficult to obtain the linearization calibration of the integral area. We have made significant breakthroughs in the design of calibration modes, calculation methods, and calibration software, which are superior to foreign instruments and have achieved good results in the full rangelinearityDomestic peers almost adopt moreair chamberThe segmented calibration has significant drawbacks and limitations in its use.

High frequency furnace program heating

sampleThe combustion temperature and the release rate of high carbon and high sulfur have a certain impact on the accuracy of analysis. At present, high-frequency furnaces on the market cannot effectively solve these problems. The high-frequency furnace produced by our company hastemperature-programmedFunction, with 32 temperature rise curves for different samples for easy access at any time. For example, the high carbon heating curve significantly reduces dust and controls the release rate of carbon compared to conventional uncontrollable power, thereby significantly improving analysis accuracy; The ultra-low content heating curve can eliminate the blank effect of carbon on the surface of the tested sample, and at the same time, through appropriate power control, increase the sample weight of the tested sample, thereby reducingfluxThe impact of blanks; By controlling the combustion temperature of the tested sample, the impact of molten samples on the combustion process can be reducedcrucibleThe corrosion eliminated the blank introduced by the release of impurities inside the crucible.
