Introduces the characteristics and features of Agilent PLgel 5 µm MIXED-D column for polyurethane analysis.
This document details the use of Agilent PLgel 5 µm MIXED-D columns for analyzing polyurethane samples. The columns are designed to resolve both high and low molecular weight components within the range of 200 to 400,000 MW. The note specifies that these columns are ideal for polymers, paints, and resin systems where material above 400,000 MW is unlikely to be present.
The document provides specific experimental conditions for the analysis, including the use of two columns (2 x Agilent PLgel MIXED-D, 300 x 7.5 mm, 5 µm), THF as the eluent, a flow rate of 1.0 L/min, and an Agilent PL-GPC 50 system. Results demonstrate the ability to determine the molecular weight distribution of polyurethane.
