Molecular Weight Markers
Since 1964 Pressure Chemical Company has been supplying a broad range of polymer standards for gel permeation chromatography (GPC) inluding Polystyrene Standards, Polyethylene Fractions and several specialty polymers and molecular weight markers.
Our narrow molecular weight polymer standards have been characterized for number, weight and viscosity average molecular weights, by GPC, light scattering and NMR, where applicable.
In addition to offering individual Polymer Standards, we also offer polymer kits with a series of standards designed for calibration curves of different molecular weights ranging from low to high.
