Gas Chromatography

In this application note, a purified polyclonal antibody (IgG) is separated using Size Exclusion Chromatography (SEC) and characterized using the Viscotek SEC-MALS 20, allowing calculation of molecular weight and radius of gyration (Rg).

Then & Now, with Katie Banaszewski, Method Development Scientist III at Now Foods, Bloomingdale, Illinois, USA.

The story behind direct mass spectrometric detection of chiral molecules using MS-PECD – a winner of The Analytical Scientist Innovation Awards (TASIAs).

The proteome is practically infinite in its complexity. If we are ever going to fully unravel its secrets, the best separation tools – and the best know-how – must be combined. Here, four experts discuss the broad importance of proteomics, the potential of multidimensional liquid chromatography, and the challenges inherent in gaining insight beyond the “tip of the proteo-berg.”

Is pesticide residue analysis still a hot topic? Ahead of EPRW 2016 in Cyprus, current Chair – Despo Louca Christodoulou – and scientific organizing committee members Magnus Jezussek and Sonja Masselter discuss the importance of the field in challenging times.

A sample of PMMA was analysed by Size Exclusion Chromatography with Triple detection, before and after sterilization. Reduction in the molecular weight was shown to be firstly by cleaving the polymer at the branching points.
