Recently, I was honored to attend the 2019 Shimadzu Global Innovation Summit, hosted by Shimadzu Corporation in Kyoto, Japan. The focus of this meeting was to highlight innovation at the interface between analytical chemistry and medicine.

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.

A new method for the accurate molecular weight determination of the complex polysaccharides chitosans has been developed using asymmetric AF4 coupled with MALS and differential RI detectors.

Researchers from the University of Huddersfield present new data and announce further studies which show great potential for the development of a for a noninvasive multiple sclerosis diagnostic tool which uses GC–MS.

The 2019 LCGC salary and employment survey extracted from calendar years 2018–2019 trends shows a slight increase in average salaries over previous years, and a narrowing of the gender gap in several categories.

To better understand modern sample preparation techniques-such as ultrasound-assisted extraction, microwave-assisted extraction, and pressurized solvent extraction-we should look at the lessons these methods took from Soxhlet extraction.

In LC–MS, the importance of tuning and calibrating the mass spectrometer cannot be overemphasized. There are six main aspects to address.

HILIC has rapidly evolved into a practical technique. For analyzing highly polar compounds, HILIC can be far more straightforward than GC or reversed-phase LC with derivatization, and can lead to a simpler final method with robustness comparable to that of reversed-phase LC.

Several regulatory data integrity guidance documents require that laboratories understand the data life cycle of their processes, but provide only vague definitions of what a data life cycle is. Here is a practical interpretation.
