Agilent Polysiloxane Analysis on Agilent PLgel 5 m MIXED-E using GPC/SEC with RI ELS Detection Manual

Update: 29 September, 2023

This application note introduces the analysis of polysiloxane using GPC/SEC with RI and ELS detection on Agilent PLgel 5 µm MIXED-E column. Polysiloxanes are important commercial polymers used in applications such as lubricating oils, defoaming agents, and sealants. Analyzing these materials by gel permeation chromatography (GPC) is an important part of process and quality control procedures. Although polysiloxane is soluble in tetrahydrofuran (THF), it has the same refractive index as this solvent. Therefore, refractive index (RI) detection cannot be used with THF.
