Sitting Down With… Andrew Whitley, Vice President of Sales and Business Development at HORIBA Scientific

Accurate measurement is the very essence of science; better measurement technologies are the fuel of progress. Here, we recognize a year’s worth of innovation in The Analytical Scientist Innovation Awards (TASIAs) 2013.

This whitepaper reviews the methods available for measuring the key characteristics of polymers focusing on the benefits and value of gel permeation / size exclusion chromatography (GPC/SEC). Much of the paper talks exclusively about polymers, however many of the principles discussed are equally applicable to proteins or protein conjugate materials.

Light scattering detectors play an important role in gel permeation chromatography and size exclusion chromatography (GPC/SEC) analysis because of their ability to directly measure molecular weight distribution. Multi angle light scattering (MALS) detectors are often chosen, in some instances because they provide the most accurate data for the measurement of the radius of gyration (Rg), and in others because they have become an accepted industry standard. The launch of Malvern Instruments’ new Viscotek SEC-MALS 20 detector extends commercial choice in this area and draws the technology into the spotlight.
