This document describes the analysis of epoxy resins using Agilent PLgel MIXED-E with Gel Permeation Chromatography. Epoxy resins are thermosetting copolymers that are widely used as general-purpose adhesives, coatings, and composites due to their durability. The analysis is straightforward with Agilent PLgel 3 µm MIXED-E columns, which can analyze low molecular weight samples as well as polymers up to 30,000 MW.
This document details the analysis of epoxy resins, which are thermosetting copolymers used as adhesives, coatings, and composites. The analysis utilizes Agilent PLgel 3 µm MIXED-E columns, which are ideal for low molecular weight samples containing oligomeric fractions and polymers up to 30,000 MW.
The procedure achieves ultra-high efficiency with baseline resolution, eluting the lowest molecular weight component within 8 minutes. The specific conditions include the use of THF as the eluent, a flow rate of 1.0 mL/min, and an RI detector on an Agilent PL-GPC 50 system.
