Superficially porous particles for HPLC columns ? often called ?core?shell? particles ? have gotten a lot of attention in recent years because of their excellent performance. Yet so far, columns made with fully porous particles are still the most widely used. Will superficially porous particles eventually take over?

Thermo Fisher Scientific (California, USA) has signed an agreement with GE Healthcare (St Giles, UK) to sell business assets for $1.06 billion. Thermo Fisher committed to sell its cell culture, gene modulation, and magnetic beads businesses in 2013 to expedite approval of its pending acquisition of Life Technologies by the European Commission.
In this new LCGC TV video, Joe Foley briefly explains how sequential LC works and its advantages over conducting multiple runs of conventional LC.
The Supervisory Board of Akzo Nobel N.V (Amsterdam, Netherlands) has announced that Keith Nichols, Chief Financial Officer, will step down from his position at the end of June 2014.
Everyone loves a list. At least, the LCGC editorial team does! LCGC?s biggest stories of the year show just how varied the world of chromatography is. From Excel modeling to evaluating a calibration curve, from trends in sample preparation to poor resolution and sample recovery in UHPLC ? these popular pieces stand for their technical know-how, unique insight, and perspective.

An assembly of thoughts on all things filtration for HPLC - and how to deal with various nasties - from Rocks to Sand.
Researcher Christina Agapakis from the University of California, Los Angeles, USA, has come up with an unusual way of making cheese by taking bacteria from various parts of the human body and analyzing the odour of each cheese produced using headspace gas chromatography?mass spectrometry (GC?MS).
Scientists in the USA have carried out an investigation into the variety of beverages enjoyed by the Northern Bronze and Iron Age peoples before written records began using a combination of analytical chemical techniques.
The National Institute of Standards and Technology (NIST), an agency of the U.S. Department of Commerce, has made a polycyclic aromatic hydrocarbon (PAH) structure index database publicly available on-line (http://pah.nist.gov/). A byproduct of hydrocarbon fuel combustion, PAHs can have significant adverse health and environmental impacts. The website contains data on more than 650 PAH compounds, with more to be added in the future.
Agilent Technologies (California, USA) has awarded a grant to the Duke Molecular Physiology Institute, Duke University (North Carolina, USA) to support the research of the metabolic and physiological aspects of major chronic diseases such as cardiovascular disease. The institute researchers perform a range of analytical chemistry techniques, including liquid chromatography and gas chromatography coupled to mass spectrometry, to characterize molecular pathways in disease.

Researchers at the University of Toronto (Toronto, Canada), funded by the Natural Sciences and Engineering Research Council of Canada, have discovered a potential long-lived greenhouse gas, perfluorotributylamine (PFTBA), that could be a contributing factor towards global climate change.1 Published in the journal Geophysical Research Letters, the study performed gas chromatography–mass spectrometry (GC–MS) and spectroscopic techniques to suggest that PFTBA can have a bigger impact on climate than carbon dioxide.
