This application note describes a method for analyzing phenolic resins using Agilent PLgel columns and gel permeation chromatography. The method can be used to analyze various types of phenolic resins, including those used in printed circuit boards, adhesives, coatings, and laboratory bench tops.
Phenol formaldehyde resins are commonly used for printed circuit boards, adhesives, coatings, and lab bench tops. This document details the analysis of two different phenolic resin samples using Agilent PLgel columns via Gel Permeation Chromatography (GPC). The method utilizes Dimethylformamide (DMF) as a polar eluent to achieve good resolution of oligomeric species.
The method is used to analyze phenol formaldehyde resins, which may include precursors such as other phenols or aldehydes.
Dimethylformamide (DMF) is a suitable polar eluent for the analysis of polar phenolic resins.
The sample shown in Figure 1 was run at a temperature of 50°C.
