Incognito is thinking long-term. Is there scope for hope in the future?

Organized by The Chromatographic Society and the Separation Science Group of the Royal Society of Chemistry’s (RSC) analytical division, the Emerging Separation Technologies meeting was held on the 28 March 2019 at the RSC’s central London headquarters in Burlington House.

Gel permeation chromatography/size-exclusion chromatography (GPC/SEC) is the standard technique to determine the molar mass distribution of synthetic macromolecules. However, some kinds of polymers (for example, polyolefins) are often only soluble in special solvents and require high temperatures to be used during the analysis to keep the sample completely dissolved. Therefore, for the analysis of these polymers, dedicated high temperature GPC systems are used. This article will discuss the pros and cons of both high temperature GPC/SEC and ambient GPC/SEC.

An excerpt from LCGC’s professional development platform, CHROMacademy.com, on the importance of tuning and calibration in liquid chromatography–mass spectrometry (LC–MS).

The Community for the Analytical Measurement Science (CAMS) was officially launched on 27 June at the Royal Society of Chemistry, Burlington House, London, UK.
