American Polymer Standards Corporation
providing Molecular Weight Determination Services,
Polymer Standards and GPC Columns since 1983
APSC is an independent contract testing laboratory specializing in Molecular Weight Distribution
analysis by various methods. These methods include Gel Permeation Chromatography/Size Exclusion Chromatography (GPC/SEC); Multi-Angle Laser Light Scattering (MALLS) and
Vapor Pressure Osmometry (VPO). Intrinsic Viscosity is also available.
APSC works closely with customers that require method development or that wish to
have their own custom methods preformed.
Polymer standards listed on this site are ideally suited for calibrating instruments and
determining molecular weights of polymer samples by applications such as
GPC/SEC, LALLS, Osmometry, Viscometry, etc...
These standards are only offered for research and investigational purposes and
are NOT intended for food, drug, cosmetic or household use.
