SH709 Automatic thiol sulfur analyzer

The SH709 thiol sulfur analyzer complies with standards such as GB/T 1792 and ASTM D3227. Suitable for determining thiol sulfur in hydrogen sulfide free jet fuel, gasoline, kerosene, and light diesel. The determination of thiol sulfur is of great significance in evaluating the odor of jet fuel, gasoline, kerosene, and light diesel, its adverse effects on rubber components of fuel systems, and its corrosion on fuel systems.

The automatic thiol sulfur analyzer adopts the principle of potentiometric titration for measurement. Dissolve the hydrogen sulfide free sample in sodium acetate isopropanol solvent, perform potentiometric titration with silver nitrate alcohol standard solution, use pH glass electrode as reference electrode, thiol sulfur electrode as indicator electrode, and the potential jump between the two electrodes indicates the titration endpoint. During the titration process, thiol sulfur precipitates as thiol silver.
