The 39th International Symposium on Capillary Chromatography (ISCC) and the 12th GCGC Symposium will be held jointly from 17–21 May 2015 in Ft. Worth, Texas, USA. This preview explains more.

Vinyl flooring in the home could be a key source of phthalates ingested and inhaled by children, according to a new study. The work was performed as part of an ongoing project by the Columbia Center for Children’s Environmental Health (CCCEH) at Columbia University in New York, USA, and followed a cohort of women and children living in New York city to investigate the impact of phthalate exposure on the health of children.

Thermo Fisher Scientific (Waltham, Massachusetts, USA) has acquired Advanced Scientifics, Inc. (ASI) (Millersburg, Pennsylvania, USA) for $300 million (US) in cash.

On Monday 2 February the New York State Attorney General’s office sent letters to four major retailers accusing them of selling fraudulent herbal supplements and demanding that they remove the products from their shelves. To the surprise of many analytical chemists, however, the accusations were based on DNA barcoding technology rather than chromatographic analysis.

PerkinElmer and Waters Collaborate

The University of Leicester and Glenfield Hospital in Leicester, UK, are starting a clinical trial into a gas chromatography–field asymmetric ion mobility spectrometry sensor (Owlstone Nanotech Ltd.) for the detection of early-stage lung cancer.

In this blog installment, I would like to share a little advice with those of you who are attending your first major conference.

Gas chromatography (GC) is often regarded as a mature technology and some say that the application base has become routine; however, conventional detectors may not be able to keep up with the speed of separations that can be achieved today. In this new video Kevin Schug from the University of Texas Arlington, USA, talks about the development of a new vacuum ultraviolet (UV) detector, from the initial idea to the fundamentals of its operation.

The 2015 Chromatography Forum of the Delaware Valley Dal Nogare Award will be presented to Mark R. Schure, adjunct professor of chemical engineering at the University of Delaware, on Monday morning at Pittcon 2015.

For the first time this year, the winners of the LCGC Awards will be honored in an oral symposium at Pittcon. Jack Kirkland of Advanced Materials Technology will receive the 2015 LCGC Lifetime Achievement Award at 1:30, and Caroline West, of the University of Orléans, will receive the 2015 LCGC Emerging Leader Award at 3:40 pm, just after the break.

This organized contributed session was arranged by Andy Miles and Paul Wrezel of Regis Technologies, Inc. Miles will preside over the session, which will start at 1:30 p.m. this afternoon.

Joseph Jack Kirkland, considered by many to be one of fathers of high performance liquid chromatography (HPLC), is the winner of LCGC’s 2015 Lifetime Achievement Award.

Shodex introduces the VG-50 4E column packed with a durable polymer based packing material modified with chemically stable tertiary amino functional groups. Shodex VG-50 4E is suitable for saccharide analysis and provides a fast reliable method for the determination of lactose and lactulose.

There has been a revival of supercritical fluid chromatography (SFC) in recent years, especially in the chiral preparative field, but also more recently in the analytical area. However, SFC is considerably more complex than liquid chromatography (LC), mainly because of the compressibility of the mobile phase. One can say that SFC is a “rubber variant” of LC where everything considered constant in LC varies in SFC. In this review, we go through advances in theory, instrumentation, and novel applications.

A stepwise process is described to help isolate and identify the cause of a method failure.

31st International Symposium on MicroScale Bioseparations

The numerous advantages of translating gradient chromatographic methods between the differing formats of LC have been explored and discussed. While translations in principle obey well defined chromatographic theories, the authors investigate a number of potential pitfalls that may result in poor translations as exhibited by selectivity differences, changes in efficiency, and hence failure to meet resolution system suitability criteria.

The transit of peaks through a gas chromatography (GC) column depends strongly on the thermal profile they encounter on the way. Gas chromatographers primarily rely on the classic hot?air?bath type of oven, but several alternatives are also in use. This instalment examines ovens for GC in several forms plus how oven thermals affect peak retention behaviour.
