Many parameters within liquid chromatography–mass spectrometry (LC–MS) methods are "locked and left" - that is, they are optimized using a few methods when new, then only changed if absolutely necessary because of poor analytical performance.

A recent stimulus to the review process article by the United States Pharmacopoeia (USP) Expert Committee is proposing a major change in the way regulated laboratories develop, validate and control analytical procedures. Is this Quality by Design (QbD) for the chromatography laboratory?

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?

Superficially porous particles for HPLC columns have gotten a lot of attention in recent years because of their excellent performance. Richard Henry discusses why fully porous particles are still the most widely used.

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.

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.

Gilles Martin, Chairman and Chief Executive Officer of the Eurofins Scientific Group (Luxembourg, Luxembourg), has been elected to the Bruker Board of Directors (Massachusetts, USA). Martin founded the original Eurofins Scientific Nantes food authenticity laboratory in 1988, and is a past President of the French Association of private analytical laboratories, and the North American Technical Committee for Juice and Juice Products.

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.

In this new video interview, Dwight Stoll of Gustavus Adolphus provides advice about key decisions in method development, common errors to avoid, and other advice for getting started with 2D LC.
