Analytical size-exclusion chromatography (SEC) often suffers from several limitations. This article shows how some of these limitations can be partly (or even completely) resolved by a multi-angle light scattering (MALS) detector for the determination of molar mass distributions of synthetic and natural polymers.

The question, which is often asked of our technical support and applications chemists, is one to which I often reply, in the words of John F Kennedy, "Ask not what your column can for you, ask what you can do for your column.” OK, JFK substituted “column” for “country” in his version of the quotation, but as you will see, it’s a very relevant premise!

Kevin A. Schug suggests that now is the time to fast-track industry–academic partnerships for greater sustainability.

A novel analysis technique has been developed for the determination of microplastics (MPs) in complex environmental samples using thermal extraction desorption gas chromatography–mass spectrometry (TED-GC–MS).
