ISO 20336 Apparatus for Total Sulfur of Solid Mineral Fuels
KN-20336 Apparatus for Total Sulfur of Solid Mineral Fuels conforms to ISO 20336 Solid mineral fuels----Determination of total sulfur by Coulomb titration method. In the presence of the catalyst, a weighed sample is combusted at 1150℃ in a stream of purified air. The sulfur oxides are formed and dissolved in the electrolytic solution. The sulfur dioxides are titrated by the iodine and bromine liberated from the electrolysis of the potassium iodide and potassium bromide solution. The quantity of the electricity consumed by electrolysis is integrated and used to calculate the content of sulfur dioxides. The instrument is calibrated with certified reference materials. The percentage of total sulfur in the sample is calculated according to the sulfur dioxides content and the prior calibration.

ASTM D4530 Micro Carbon Residue Apparatus
The carbon residue value of the various petroleum materials serves as an approximation of the tendency of the material to form carbonaceous type deposits under degradation conditions similar to those used in the test method, and can be useful as a guide in manufacture of certain stocks. However, care needs to be exercised in interpreting the results
