The characterization of paint in famous artworks is valuable for investigating the painting techniques used by artists, for conservation purposes and to help repair damaged paintings. By combining HPLC–ESI-QTOF-MS with traditional analytical techniques, researchers were able to clarify the composition of the oil components and hypothesize the botanical origin of the lipid materials used by Edvard Munch.

Kevin Schug discusses why we need a comprehensive study of unconventional oil and natural gas (UOG) extraction processes.

“A Toolbox for LC–MS Protein Analysis” from EMD Millipore will be held on 17 and 18 November 2015.

Populations worldwide are exposed to polychlorinated biphenyls (PCBs) that can be harmful to human health. The Column spoke to David Megson from Ryerson University in Toronto, Canada, about recent developments in assessing human exposure to PCBs and chiral enantiomer fractions (EFs) in the workplace.

The second part of the review on the two-day symposium focusing on the characterization of biopharmaceutical molecules at AstraZeneca’s MedImmune site in Cambridge, UK.

A new method for the simultaneous determination of emerging and persistent organic pollutants (POPs) in fish bile samples has been developed using gas chromatography–mass spectrometry (GC–MS).

Accounting for the inherent heterogeneity of monoclonal antibodies is essential to ensure production of consistent and safe therapeutics and, in light of this, there is an array of chromatographic and supporting regulatory systems. Robust characterization and analysis of monoclonal antibodies is becoming a fast and straightforward process thanks to the myriad technological advances underpinning this rapidly evolving area.
