This application note describes a conventional GPC method for the analysis of melamine resins using Agilent PolarGel-L columns and the Agilent PL-GPC 50 system.
Melamine resins are durable thermosetting plastics used in various applications, including furniture and food packaging. Accurate characterization of their molecular weight distribution is essential for determining end-use suitability.
The document details a method using the Agilent PL-GPC 50 Integrated GPC/SEC System with two PolarGel-L columns (7.5 x 300 mm) to analyze melamine resin samples. The analysis utilized dimethylacetamide + 0.1% LiBr as an eluent at a flow rate of 1.0 mL/min and a temperature of 50°C.
The flow rate used for the analysis is 1.0 mL/min.
The analysis should be performed at a temperature of 50°C.
The required eluent is Dimethylacetamide plus 0.1% LiBr.
