Abstract

Two kinds of commercially available, microparticulate silica columns have been studied for their efficiency and reproducibility in gel permeation chromatography measurements. Results are provided for column plate height measurements, dispersity, and specific resolution as a function of flow rate. The influence of injection volume and slice width on these measurements is also presented. Reproducibility studies on polystyrene and styrene‐n‐butyl methacrylate copolymer are reported.
