This document describes how to use Agilent PLgel 5 µm MIXED-D columns to analyze polyaniline.
The document details the use of Agilent PLgel 5 pm MIXED-D columns for analyzing polyaniline, specifically the emeraldine and leucoemeraldine forms. It explains that these columns are ideal for polymers where material above 400,000 MW is unlikely to be present.

Polar organic solvents such as dimethylformamide, dimethyl sulfoxide, and N-methyl-2-pyrrolidinone (NMP) are required.
High temperature is needed due to the increased viscosity of these solvents compared to tetrahydrofuran.
