Sulfur Analyzer Fully automatic sulfur analyzer, using the principle of microcoulomb titration, can be used to determine the sulfur content in crude oil, residual oil, and heavy oil. The instrument is widely used in coal, electricity, energy, mining and metallurgy, additives, environmental protection, petrochemical and scientific research departments.

2. Principle
1 Potassium iodide (GB 1272-77): analytical grade.
2 Potassium bromide (GB 649-77): analytical grade.
3 Glacial acetic acid (GB 676-78): analytical grade.
4 Tungsten trioxide: chemically pure.
5 Color-changing silica gel: industrial product.
6 Sodium hydroxide (GB 629-77): chemically pure.
7 Electrolyte: 5g each of potassium iodide and potassium bromide, 10mL of glacial acetic acid, and 250~300mL of distilled water.
1. After connecting the power supply to the fully automatic sulfur analyzer, heat the high-temperature furnace to 1150°C. Take another set of calibrated platinum-rhodium-platinum thermocouple pyrometers to measure the position and length of the high-temperature zone in the combustion tube and the pre-decomposed temperature at 600°C. Location,
2. Adjust the program controller of the fully automatic sulfur analyzer so that the pre-decomposition and high-temperature decomposition positions of the sulfur analyzer are respectively at 600°C and 1150°C in the high-temperature furnace.
.3 Fill the combustion tube with aluminum silicate wool with a thickness of 3mm, located at the rear end of the high temperature zone. Fill the exit of the combustion tube with clean and dry glass fiber wool.
.4 Assemble the sulfur meter program controller, high-temperature furnace (with built-in combustion tube), Coulomb integrator, stirrer, electrolytic cell and air purification system. The glass port of the combustion tube, piston and electrolytic cell must be aligned with each other. Seal with silicone rubber tube.
5. Start the air supply pump of the sulfur meter, adjust the pumping speed to 1000mL/min, and then close the piston between the electrolytic cell and the combustion tube. If the pumping speed drops below 500mL/min, it means that the electrolytic cell, dry smoke tube and other components are airtight. Otherwise, the electrolytic cell and other components need to be rechecked.
6 Control the furnace temperature of the sulfur meter at 1150±5°C
7. Adjust the pumping speed of the air pump of the sulfur meter and automatic sulfur meter to 1000mL/min, and pour 250~300mL of electrolyte into the electrolytic cell under air supply and air extraction conditions. After starting the stirrer, turn the knob to the automatic electrolysis position.
8. Weigh about 0.05g of the coal sample with a particle size less than 0.2mg in the boat (weigh accurately to 0.0002g), and cover the coal sample with a thin layer of tungsten trioxide. Place the boat on the quartz tray for sample delivery, turn on the program controller, the quartz tray will automatically enter the furnace, and the coulomb titration will begin immediately. The integrator will display the grams of sulfur or the printer will print out the percentage of sulfur.
Sulfur Analyzer Fully Automatic Sulfur Determination Instrument has a high degree of automation and is easy to operate: it has a continuous automatic sample delivery mechanism and can add samples continuously at any time, greatly reducing the work of the laboratory technician. The results of the sulfur analyzer are accurate and fast: no correction and transition are required; a double-layer combustion tube is used, and the sample is secondary burned in the furnace to ensure that the results of the sulfur analyzer are accurate. Advanced temperature control technology. The sulfur analyzer fully automatic sulfur determination instrument adopts new imported lightweight insulation materials, and the temperature rise accuracy can reach +3″ºC, and special can reach ±1ºC. The intelligent self-diagnosis and self-protection design make the instrument stable and adaptable to various chemical experiments. The sulfur analyzer fully automatic sulfur determination instrument is automatically controlled by a microcomputer, and various corrections and processing are performed on the test data. Automatic control of furnace flow size, automatic electrolysis switch and other functions. Sulfur Analyzer Fully Automatic Sulfur Determination Instrument Main Technical Indicators
