This document describes how to use Agilent PLgel columns for polyolefin analysis with GPC/SEC.
This document provides a technical overview for selecting the correct Agilent PLgel column set for the analysis of polyolefins using Gel Permeation Chromatography (GPC). It explains that column selection depends on the molecular weight range of the sample, with low molecular weight samples requiring high efficiency columns and higher molecular weight materials requiring large particle size media.
| PLgel 3 um 100A MW operating range | Up to 4,000 |
|---|---|
| PLgel 5 um MIXED-D MW operating range | 200—400,000 |
| PLgel 10 um MIXED-B MW operating range | 500—10,000,000 |
| PLgel 20 um MIXED-A MW operating range | 2,000—40,000,000 |
Gel permeation chromatography (GPC) is widely accepted as the preferred technique.
High efficiency, relatively low pore size columns are recommended for low molecular weight samples.
Large particle size media with a wide pore size distribution is required to minimize shear effects.
