SYD-387 Dark Petroleum Product Sulfur Content Tester (Tube Furnace Method)Detailed product description：

SYD-387 Dark Petroleum Product Sulfur Content Tester (Tube Furnace Method)
Purpose:
This instrument is designed and manufactured according to the requirements of the People's Republic of China standard GB/T387 "Determination of Sulfur Content in Dark Petroleum Products (Tube Furnace Method)", and is suitable for determining the sulfur content in dark petroleum products according to the method specified in GB/T387 standard.
This instrument uses a quartz boat containing a sample to undergo complete combustion in a constant flow of purified high-temperature hot air. A solution of hydrogen peroxide and sulfuric acid is used to fully absorb the generated sulfite and sulfuric anhydride, and the generated sulfuric acid is titrated with a standard solution of sodium hydroxide.
