METHOD OF DETERMINING ELEMENTAL SULFUR IN HYDROCARBON MEDIA Russian patent published in 2020 - IPC G01N30/00 

Abstract RU 2721894 C1

FIELD: chemistry.

SUBSTANCE: invention relates to analytical chemistry, specifically to a method for qualitative and quantitative determination of elemental sulfur in hydrocarbon media. Method of determining elementary sulfur in hydrocarbon media using a liquid chromatograph, characterized in that the stationary phase used is a non-polar sorbent, and the movable phase used is isopropyl alcohol or isopropyl alcohol : water mixture, wherein the volume ratio of alcohol and water is from 99.9 % : 0.1 % to 40 % : 60 %.

EFFECT: high sensitivity of the method of determining elemental sulfur in hydrocarbon media.
