GPC Molecular weight (mw) polymers

Intertek has long term experience in the molecular weight determination of polymers and plastics. By performing GPC analysis we determine the number-average molecular weight (Mn), mass-average molecular weight (Mw), z-average molecular weight (Mz) and Polydispersity / Molecular weight distribution (MWD) of a broad range of polymers and plastics. Intertek delivers molecular weight data for process optimization, characterization of newly developed polymers, research project support and product quality control.

Molecular weight determination services by Intertek Polychemlab include:

• MW of polymers, soluble in organic solvents (eg. THF, Toluene, Chloroform, DMF, and others)
• GPC (Gel Permeation Chromatography) / SEC (Size Exclusion Chromatography) of organic soluble polymers with MW ranging from 100 - 10.000.000 g/mol.
• Conventional (calibration based) GPC-DRI (Differential Refractive Index detection) with polystyrene-standard (PS)-calibration or polymethylmethacrylate standards (PMMA)-calibration.
• GPC-UV detection.
• characterisation of polymers (rheologic properties, optical properties, mechanical properties)

The Intertek worldwide laboratory network provides the following MW-determination (related) services:

• Gel Permeation Chromatography (GPC)
• GPC-UV / RI / SFD / Viscosimetry / ELSD / light scattering detection.
• Multi Angle Laser Light Scattering (MALLS)
• MALDI TOF-MS
• HT- GPC

MWD determination of a broad range of polymers and plastics:

• Acrylics, acrylates, polystyrene, rubbers
• Polycarbonates, polysiloxanes
• Resins, Epoxy resins, polyester resins, silicone fluids
• Prepolymers, resins, polyols, siloxanes
• etc.
