This article describes the analysis of dialkyl phthalates using gel permeation chromatography on Agilent PLgel 3 µm columns. The method is suitable for analyzing low molecular weight polymer additives such as dialkyl phthalates.
This document details the analysis and quantitation of dialkyl phthalates, which act as plasticizers in commercial polymers. Agilent PLgel 3 µm 100A columns are specifically designed to exclude polymers with molecular weights over 4,000 g/mol, allowing for the resolution of low molecular weight additives.
