Determining which gel permeation/size exclusion chromatography (GPC/SEC) system is best for your needs can be a daunting task. Even after you’ve decided to include a light scattering detector to obtain absolute molecular weight data you’re still left to choose between…READ MORE >

Atelier dans notre agence de Lyon mardi 12 juin Journée sur la chromatographie d’exclusion de taille pour les protéines (ou de perméation de gel pour les polymères) dans notre agence de Lyon. Vous seront présentés différents systèmes de détection UV, réfractomètre,…READ MORE >

GPC detector – OMNISEC – Your Questions Answered Thanks so much to those of you who joined us for the launch of  OMNISEC, our new GPC/SEC system.  If you missed the event you can play it back by clicking here, to…READ MORE >

When is Single Angle Light Scattering (LALS/RALS) the right detection technique to use, and when do you need Multi Angle Light Scattering (MALS)? Size Exclusion Chromatography (SEC) is a well-established tool for the measurement of the molecular weight and purity of…READ MORE >

Refractive index increment dn/dc values when you need them? In light scattering a crucial parameter which appears together with the Rayleigh Ratio RΘ is the refractive index increment, also known as “dn/dc”. Typically, Kc/RΘ is plotted versus concentration to extrapolate…READ MORE >

My colleagues Kevin Mattison, Mark Pothecary and I gave a short course at Peptalk 2013 in Palm Springs, CA, last week. Attendees from Europe, Australia and the US proved to be a lively and participating audience in the Pueblo Meeting…READ MORE >
