Determination of Sulfur Dioxide Mass Concentration in Ambient Air
Determination of the mass concentration of sulfur dioxide in ambient air Details:

Name: Packed column
Stationary phase: dedicated
Specification: 2m*3mm
Material: PTFE tube
Model: HH-Sulfur dioxide

The nature of sulfur dioxide Sulfur dioxide is one of the earliest chemical agents used. It was used as a bleaching agent and insecticide 4,000 years ago. At present, the production of SO 2 exceeds 100,000 tons, and about 60 million tons and 400 billion tons of CO 2 enter the atmosphere due to the combustion of coal and oil.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed a more sensitive, fast and convenient gas chromatography detection method for the determination of SO2 in the air. The HH-Sulfur dioxide chromatographic column has good separation effect and good sample stability. It has no obvious influence after storage for 1 week. The relative deviation of 8 samplings was 1.4%, and the recovery rate of standard addition was 97%-107%. Conclusion: Gas chromatography analysis of SO2 in the air is simple, sensitive, fast and accurate. It is a recommended method.

This column has high efficiency and good separation. Hydrogen sulfide, carbonyl sulfide, carbon disulfide, methyl mercaptan, and thiophene do not interfere with SO2, and the peak shape is symmetrical.
