| Function: | Total Sulfur In Coal Test | Method: | Coulometric Titration Method |
|---|---|---|---|
| Standards: | GB/T214 | Category: | Coal Coke Analysis Instrument |
◎ The horizontal integrated structure is adopted to skillfully combine the automatic sample feeding, sample injection mechanism, high-temperature cracking furnace, electrolytic cell, agitator, air purification system and other components, making the instrument more compact, reasonable and stable;
◎ Special flat bottom corundum porcelain boat is used to reduce the possibility of sample jamming. Automatic temperature rise, temperature control, sample delivery and measurement are realized by program control. The results are automatically saved and printed, and samples can be added in the middle, which greatly improves the work efficiency and truly realizes unattended;
◎ The coulometric titration method is adopted for the determination. The determination time can be automatically judged according to different samples, and the speed is superior to the Eska gravimetric method and the high-temperature combustion neutralization method;
◎ Adopt linear electrolyte molecular concentration collection circuit to effectively solve the over electrolysis problem;
◎ Contactless switch is adopted, with measures of couple breaking protection, hardware over temperature protection and electrolyte backflow prevention;
◎ Multi point dynamic coefficient correction method is adopted to ensure higher accuracy of coal test results with high, medium and low sulfur content;
◎ It can be connected to the laboratory management system to ensure that the balance data does not fall to the ground, and the test results are backed up and uploaded;
◎ It can be used to determine the total sulfur content in solid hazardous waste and other samples.
