GC-MS helps to create aged spirits… in only six days

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.

In this application note, a selection of proteins are separated using Size Exclusion Chromatograpghy (SEC). The molecular weights of their oligomers and aggregates are measured by SEC-MALS and the results discussed.

For over 50 years, we have been continually striving to push the limits of quantitation for dioxins. But where do we stand today – and what’s our next plan of attack?
