Overview:
The instrument uses the dynamic microcoulometry principle: the sample to be tested undergoes redox reaction after combustion in the pyrolysis tube, and the reactant gas (HCL) is brought into the titration cell by the carrier gas into the titratable ion CL- and reacts with the Ag + By measuring the amount of Ag + consumed during the electrolytic titration, the total chlorine content of the sample can be obtained according to Faraday's law.
Scope of application: It is used for total chlorine content analysis of samples in the fields of production, scientific research and monitoring of petroleum, petrochemical industry, medicine, health, environmental protection, coal, geology, metallurgy, commodity inspection, quality inspection and school. Meets the Standard: GB / T 18612 Determination of Organic Chlorine Content of Crude Oil ASTM D5808 Test Method for Chlorides in Aromatics and Related Compounds by Microelement Analysis ASTM D4929 Test Method for Determination of Organochlorine in Crude Oil. The most advanced total chlorine content analysis instrument in the country has reached the advanced technical level of similar products in the world and has been replaced by imported ones and exported to Kazakhstan and other countries with major national projects.
Instruments for the PetroChina, Sinopec, CNOOC sales shortlisted products. Features:
1Windows operating platform, man-machine direct dialogue, easy to operate.
2 computer control the entire analysis, data processing and other processes, showing the whole process of working conditions, according to need parameters, the results save or print. Software can save 5000 samples of data, enabling historical data query and graphics playback, easy to control analysis.
3 instruments using international popular circuit and imported components, reducing the instrument noise and improve the detection sensitivity.
4 analysis speed, analysis of a sample just 3-4min
5 instrument measurement accuracy, stability, repeatability error is better than GB / T0689 analysis error requirements.
6 to overcome the traditional Coulomb instrument on the water quality requirements, the conversion rate is low, the upgraded equipment to reduce the water quality and other analytical conditions, the standard conversion rate of 90% to 110%, the same standard anti-standard The error is not more than 5%.
7 imported high-quality heating wire, cracking furnace longer life. Data processing software with automatic over-temperature protection cut off function. Prevent burn out electric furnace wire and combustion tube because over-temperature.
8 delay cooling function, the analysis can be set after the wind cooling time, automatically shut down when the power, without human waiting.
The 9-character, high-performance spiral burner is especially suitable for the detection of halogens in various liquid gaseous samples containing highly volatile components. The main advantages of the combustion tube: injection speed (maximum 1ul / s), not easy to coking, help to improve the accuracy of the analysis results and trace sample analysis.
10 chlorine titration tank unique design, the use of all silver rod electrode, without prior preparation. The titration cell is stable for a long time, not less than 4 hours. The titration cell contains 75% glacial acetic acid and the capacity is 35ml. It can analyze multiple samples without maintenance, with accurate measurement, short start-up time and small maintenance. The detector is equipped with an independent temperature control and the titration cell is stable for a long time to keep the temperature of the titration cell constant. After testing the gas can be discharged through the hose connection to the outside or into the distilled water bottle adsorption.
