Analysis of many polymers has an additional complication
in that apart from determination of functional groups, etc, such compounds do not vary in chemical composition but their functionality varies as a function of molecular size. Therefore Size Exclusion Chromatography (SEC) can be employed to further characterise polymeric materials.

SEC is divided into Gel Permeation Chromatography (GPC) which is performed using organic mobile phases and Gel Filtration Chromatography (GFC) which is carried out in aqueous eluent systems.

The silica is derivatised with 1,2-dihydroxypropane and, with the variety of pore size available, allows analyses over a broad range of peptide to large proteins

YMC-Pack Diol stationary phases are surface modified for a versatile alternative to underivatised silica. Advantages include a shorter equilibration time as well as good selectivity. Due to this short equilibration time, the Diol phase is a good choice for SEC in comparison with underivatised silica.
