FLYC-5Fluorine and chlorine element analyzer for coal

Product Overview:

This experimental equipment uses a high-temperature combustion hydrolysis method to obtain fluoride and chloride ion sample solutions. The fluoride electrode is used as the indicator electrode, and the saturated calomel electrode is used as the reference electrode. The fluoride ion concentration in the sample solution is measured using the standard addition method, and the fluoride and chloride content in coal is calculated, which meets the requirements of the national standard "Determination Method for Fluorine and Chlorine in Coal".

Testing principle:

Coal samples are mixed with a small amount of quartz sand and burned and hydrolyzed in a gas stream mixed with oxygen and water vapor at a high temperature of 1100 ℃. Various forms of fluorides in coal are converted into volatile fluorides and quantitatively dissolved in water. The fluoride electrode is used as the indicator electrode, and the saturated calomel electrode is used as the reference electrode. The fluoride chloride ion concentration in the sample solution is measured using the standard addition method to calculate the fluoride chloride content in coal.

Functional features:

1. Adopting Chinese LCD display, the interface is friendly and the operation is simple.

2. Adopting PID control for furnace flow, with high temperature control accuracy, effectively extending the service life of silicon carbon tubes.

3. High precision and low-temperature drift components are used for temperature measurement, ensuring long-term accuracy.

4. On the basis of the first generation equipment, this instrument has improved the sample delivery device, changing from manual sample delivery to continuous automatic sample delivery, avoiding the disadvantages of manual sample delivery and easy cracking of the reducer due to explosion.

5. Supporting timed sample delivery reminder function, sample delivery is more stable and continuous, improving the accuracy of inspection results and simplifying the operation procedures for experimental personnel.

6. Support fault self diagnosis function and over temperature protection function.

7. The evaporation adjustment potentiometer adopts Taiwan TOCOS potentiometer, which has high linearity and long service life.

8. Configuring a high-precision digital ionizer ensures the accuracy of the experiment.

9. The automatic calculation software for the delivery upper computer inputs experimental data and automatically generates measurement results, eliminating the need for complex calculation processes for users. It saves data, makes queries convenient and concise, and provides clear and centralized information at a glance.

10. The test sample includes a refrigeration cycle system, and the next sample can be tested without cooling.
