The Satinder Ahuja Award for Young Investigator in Separation Sciences has been presented to Matthew Miller, Technical Leader at Dow Chemical in the Analytical Science Core R&D group, at Pittcon 2016.

The 31st International Symposium on Chromatography (ISC 2016) will be held from 28 August–1 September 2016 at University College Cork, Cork, Ireland.

A team of researchers has developed a high-throughput analysis method for 192 diverse pesticides and 51 environmental contaminants (13 polychlorianted biphenyl [PCB] congeners, 14 polycyclic aromatic hydrocarbons [PAHs], seven polybrominated diphenyl ethers [PBDE] congeners, and 17 novel flame retardants) in cattle, swine, and poultry meats. The team used a combination of low-pressure gas chromatography coupled to tandem mass spectrometry (LP)GC–MS–MS and ultrahigh-pressure liquid chromatography coupled to tandem MS in the analysis.

The 2016 Pittsburgh Conference Achievement Award was presented to Jared L. Anderson, professor of chemistry at Iowa State University, at Pittcon 2016.

The 2016 Chromatography Forum of the Delaware Valley Dal Nogare Award was presented to Stephen Weber, professor of chemistry and clinical translational science at the University of Pittsburgh, at Pittcon 2016, held this year in Atlanta, Georgia.

What is required to produce a highly efficient modern high performance liquid chromatography (HPLC) system/column combination? This instalment of the LCGC Blog explains more.

Waters Corporation and BioCity have celebrated the opening of a new open access analytical laboratory located in the BioHub at Alderley Park, Cheshire, UK.

A preview of The Chromatographic Society’s first meeting in 2016, which will take place on Tuesday 22 March in London, UK.

Researchers studying necrophargous blowflies for forensic investigations have developed a novel gas chromatography–mass spectrometry (GC–MS) method for the detection of nicotine. Nicotine has been attributed to a number of accidental or sudden, suicidal, and homicidal deaths.

A team of researchers from China and the USA has developed a LC–MS–MS method for quantifying methylergonovine, a semi-synthetic ergot alkaloid used for the treatment and prevention of postpartum haemorrhage in human plasma.

How suitable is the column plate number for system suitability testing?

Thermal desorption sampling often provides a means for bringing otherwise intractable samples to a gas chromatography (GC) column for separation and detection. In this instalment, John Hinshaw describes the principles of thermal desorption sampling in relationship to other analysis techniques for volatile solutes.

The literature on reversed-phase liquid chromatography of proteins is reasonably well developed, but not taught in the college classroom to a significant degree. So I would like to focus on a stoichiometric displacement model for reversed-phase LC of proteins that I found to be particularly insightful from a practical standpoint.

This afternoon, the winners of the LCGC Awards will be honored in an oral symposium at Pittcon. Milton L. Lee of Brigham Young University will receive the 2016 LCGC Lifetime Achievement Award at 1:30, and Debby Mangelings of the Free University of Brussels (Vrie Universiteit Brussel), will receive the 2016 LCGC Emerging Leader Award at 3:45 pm, just after the break. The symposium will be held in room B314.

The 2016 Chromatography Forum of the Delaware Valley Dal Nogare Award will be presented to Stephen Weber, who is a Professor of Chemistry and Clinical Translational Science at the University of Pittsburgh, on Monday morning at Pittcon 2016. The award will be presented by Mary Ellen McNally of EI DuPont de Nemours and Company. The Chromatography Forum of the Delaware Valley chooses award recipients based on their contributions to the fundamental understanding of the chromatographic process. The award was established in honor of Stephen Dal Nogare, who died in 1968 after serving for six months as president of the Chromatography Forum.

This Monday morning session will be presided over by Archana Kumar of Genentech (San Francisco, California).

The 2016 Pittsburgh Conference Achievement Award will be presented to Jared L. Anderson, who is a Professor in the Department of Chemistry at Iowa State University, on Monday morning at Pittcon 2016. The award will be presented by Elias S. Absey, the chair of the Society for Analytical Chemists of Pittsburgh (SACP). The Pittsburgh Conference Achievement Award is presented annually by the SACP at Pittcon to recognize individuals for outstanding achievements in the fields of analytical chemistry or applied spectroscopy within 10 years after completion of their PhD work.

The sensitive, selective, and real-time analysis characteristic of the SIFT-MS technique provides simple, robust, and continuous analysis of extremely diverse odor compounds at trace levels in air. This application note illustrates instantaneous, broad spectrum odor analysis with monitoring data from a chicken meat production facility.

How suitable is the column plate number for system suitability testing?

Chromatographers often use the terms carrier-gas flow and velocity interchangeably when discussing column parameters. In liquid chromatography, the two terms scale together, but in gas chromatography they do not. This month’s “GC Connections” investigates the reasons for this non-intuitive behaviour and how it affects best practices for gas chromatographers.

The power of nontargeted metabolite profiling is illustrated in a study focused on the determination of molecular markers in malting barley that are predictive of desirable malting quality for brewing applications.
