Sulfur Content Test Apparatus (Quartz Tube Method)

Summary

The working principle:burn the sample in air flow,absorb produced sulfurous acid anhydride with hydrogen peroxide and sulfuric acid,and titrate sulphuric acid with Sodium hydroxide standard solution.

This sulfur content test apparatus is suitable for dark petroleum products with sulfur content higher than 0.1%(m/m),such as lubricating oil,heavy petroleum,crude oil,petrol coke,Paraffin,sulphur-containing additives.
