This application note describes the method for analysis of melamine resin with Agilent PLgel columns and gel permeation chromatography (GPC).
The document details an application for analyzing melamine resins, a hard thermosetting material used in tableware and laminated boards. It explains that melamine is produced by heating urea to form cyanic acid, which then polymerizes. The note highlights the resin's properties, including its high nitrogen content and fire retardant capabilities when further polymerized with formaldehyde.
Dimethylformamide (DMF) is the suitable polar solvent for this analysis.
An elevated temperature of 80 °C is recommended for the analysis.
