Agilent PLgel 5 µm Dialkyl Phthalate Analysis Application Note

About this manual

Phthalates are widely used as softeners for polyvinylchlorides but face increasing scrutiny due to health concerns. This document outlines a straightforward method for their analysis using gel permeation chromatography (GPC) with an Agilent PLgel column.

The procedure utilizes a single high-performance, low pore size Agilent PLgel 5 µm column (300 x 7.6 mm). Analysis is performed at a flow rate of 1.0 mL/min with a Refractive Index (RI) detector to achieve rapid separation and good resolution for small-molecule dialkyl phthalates.
