Does anyone have any experience with MHE? I must analyse a grafted polyvinylbenzene with respect to residuel solvants (methanol,acetone and diisopropylether) and the starting materiel (dimethyltetradecylamine;;;non volatile). I know the theory, I have the right machine (PerkinElmer Turbomatrix), the right chromatographique conditions for the analysis. What I need is practical advice on how to prepare the standards and the polymer analysis itself. Any help would be appreciated.
