This application note describes the advantages of using Agilent PLgel 10 µm MIXED-B columns for high MW polymer analysis under demanding eluent conditions such as high temperature gel permeation chromatography (GPC).
Agilent Technologies presents an application note on analyzing polyethylene terephthalate (PET) samples. The document explains that because PET has a high viscosity in the eluent, high temperature gel permeation chromatography (GPC) is necessary to maintain the polymer in solution.
The study utilized three grades of PET with different intrinsic viscosities analyzed on PLgel 10 um MIXED-B columns. These columns are designed for high molecular weight polymer analysis under demanding conditions and feature a wide range of molecular weights up to 10 million.
