RPP-300AMicrocoulometric sulfur and chlorine analyzer

Product Description：

RPP-300AMicrocoulometric sulfur and chlorine analyzerApplying the principle of microcoulometric titration, computer-controlled data acquisition and processing.The instrument adopts the principle of microcoulometry,The sample is carried into the cracking tube by the carrier gas and fully burned with oxygen, where sulfur or chlorine is quantitatively convertedConverted into titratable ions, carried into the titration cell by the carrier gas for titration, consuming the titrant in the electrolyte, generating and consuming an equal amount of titrant through electrolysis, measuring the amount of electricity consumed during the electrolysis process, and calculating the content of the element to be measured in the sample according to Faraday's law. According to different configurations, the content of sulfur or chlorine in the sample can be measured separately.RPP-300AMicrocoulometric sulfur and chlorine analyzerUsed for the determination of total sulfur or total chlorine content in products such as petrochemicals, coal chemicals, aromatic hydrocarbons, and natural gas. It has the advantages of high sensitivity and good repeatability.

Performance characteristics:

1. The quartz cracking tube is made of imported high-purity quartz material,kindThe product is fully cracked and the reaction is rapid. The use of high-precision quartz cracking tubes can increase the injection volume, improve the accuracy and repeatability of detection.

2. Temperature control system: Air cooling replaces water cooling, and the cooling fan automatically switches on and off, eliminating the need for personnel to wait for shutdown,The instrument triggered an over temperature alarm and automatically corrected it, eliminating the possibility of the cracking furnace easily burning out. The cracking furnace adopts imported electric furnace wire and three-stage heating method, with a controlled temperature between 900 ℃ and 1200 ℃.The use of low-voltage power supply effectively reduces the total power and extends the service life of the furnace.

3Adopting imported dehydration and drying tubes with heating modules(implement),Maximized the removal of water vapor generated after sample oxidation, ensuring the conversion and recovery rate of sulfur in the sample.

4The sample is thoroughly cracked and the reaction is rapid. The electrolytic cell and quartz tube adopt advanced technology, and the high-precision quartz cracking tube can increase the injection volume, improve the accuracy and repeatability of detection.

5The sampler adopts wheel injection and imported stepper motor for precise control, with no noise during injection.

6. Adopting corrosion-resistant electrode caps to avoid the problem of large detection result errors caused by electrolyte corrosion of electrode caps and poor electrode contact.

7Gas stabilization system：A pressure stabilization system has been installed in the gas circuit to avoid interference from fluctuations in gas pressure on the measurement；The gas pipeline adopts imported passivated stainless steel pipeline to reduce adsorption.

8The sampler adopts wheel injection and imported stepper motor for precise control, with no noise during injection.

9. Syringe injection system: The injection speed is constant and can be adjusted according to the sample

10. Data processing:Fully computer-controlled throughout the process,Display the entire process status, parameters, measurement peak shape, and test results. Parameter setting, calibration, and sample testing are performed on the same interface. Equipped with automatic calculation function for concentration and content,Can query, store, print spectra and test results.
