Abstract

Abstract Elemental sulfur exhibits a pronounced reversed-phase effect on styrene-divinylbenzene packings and this selective interaction can be used for the analysis of elemental sulfur by high-speed liquid chromatography. Absorption at 254 nm offers sensitive detection (1-10 ng) and calibration curves are linear up to 10-20 μg. Examples are given for the analysis of sulfur in oil and in aqueous media. Some of the parameters (packing pressure, column diameter and pore size) have been examined for this small (15-37 μm), spherical packing and a recommended packing procedure is given.
