Polymer Analysis
Gel Permeation Chromatography (GPC) – also referred to as Size Exclusion Chromatography
(SEC) – is widely used for characterizing polymers in quality control and research laboratories.
The technique has applications in many areas because of its ease of automation and quality of
the results it produces. It provides average molecular weights and molecular weight
distributions, which are calculated from the chromatogram.
Agilent Technologies is a leading supplier of equipment for GPC-SEC, offering a wide
range of supplies.
• GPC-SEC start-up kits to get you up and running quickly and easily
• EasyCal Vial calibration standards for rapid and convenient calibration
• Certified/proven columns for organic and aqueous GPC-SEC
