Gel Permeation Chromatography (GPC), also known as Size Exclusion Chromatography (SEC), is the most common analytical technique for the measurement of molecular weight distribution, structure and viscosity of a wide variety of polymers. Multi-Detector GPC/SEC, coupled with novel chromatographic techniques such as Malvern's SELS (Solvent Enhanced Light Scattering) technology, has provided a new approach to fully characterizing polymeric systems and addressing difficult chromatography and detection issues.

In this webinar the application of GPC to measure challenging 'invisible' polymers is presented. While several polymers (e.g. Fluoro-Polyester PMTFMA in THF, PHA in chloroform, olefin rubbers in xylene, polymers in HFIP) have been difficult to measure due to low dn/dc refractive index increment values or safety concerns, the unique SELS method still allowed reliable determination of Mw, Mn, and PDI — parameters that are important for characterizing polymer quality and improving product output in a manufacturing process.

What Attendees Will Learn:


• How to use multi-detector GPC/SEC to enhance the information content available in the GPC/SEC experiment

• How to use novel chromatographic techniques to solve GPC/SEC chromatography, detection and associated HS&E issues

• How to employ good chromatography practices as a prerequisite for data accuracy in GPC/SEC measurements
