Gel-Permeation Chromatographic And High-Performance Liquid-Chromatographic Analyses Of Elemental Sulfur In Transducer Elastomers
Gel permeation chromatographic (GPC) and reversed-phase high-performance liquid chromatographic (RP-HPLC) methods were developed for measuring the level of elemental sulfur in an uncured, compounded nitrile rubber formulation. The sulfur content in 17 uncured nitrile rubber samples was measured using the American Society of Testing and Materials (ASTM) procedure D-297 and the GPC procedure. The results were compared and are discussed. The sulfur content of a second set of uncured, compounded nitrile samples was measured using the GPC and RP-HPLC methods. It was found that both chromatographic methods yielded results that were comparable in precision and level of sulfur recovered. The advantages of the chromatographic methods over the ASTM procedure are discussed.
