Absorb the generated sulfur oxides in hydrogen peroxide! Neutralize with sodium hydroxide standard solution and determine the sulfur content using a sulfur content tester.
The "QS Series" is an automatic combustion tube sulfur content tester that introduces air into a quartz combustion tube heated to 950–1100°C to combust the sample. The generated sulfur oxides are absorbed in hydrogen peroxide (3%) to form sulfuric acid, which is then neutralized and titrated with sodium hydroxide standard solution to determine the sulfur content. This device automatically performs the combustion process of the sample. 【Features】 ■ Two models: QS-AC1 type (single combustion tube holder) and QS-AC2 type (dual combustion tube holder) ■ The fixed furnace maintains a constant testing temperature, allowing for repeated tests ■ The movable furnace is a quick-cooling split type, enabling the starting temperature to be adjusted based on the sample, accommodating various samples ■ The combustion process is automated, allowing for evaporation combustion without igniting the sample ■ The combustion speed in the combustion section can be manually adjusted with a switch ■ The flow meter is equipped with a needle valve to regulate the specified amount of air *For more details, please refer to the PDF document or feel free to contact us.
