Since 1964 Pressure Chemical Company has been supplying a broad range of polymer standards for gel permeation chromatography (GPC) including polystyrene standards, polyethylene fractions and several specialty polymers and molecular weight markers.
Our offerings of narrow molecular weight polymer standards have been characterized for number, weight and viscosity average molecular weights, by gel permeation chromatography (GPC, light scattering) and nuclear magnetic resonance spectroscopy (NMR), where applicable.
