We recently spoke to Gary Duncan and Wendy Russell of the Rowett Institute of Nutrition & Health in Aberdeen, Scotland, about the significance of phytochemical bioavailability to human health and the important role of liquid chromatography linked to tandem mass spectrometry (LC–MS-MS) in their research.
A multiresidue method has been developed and validated for the analysis of methylxanthines (caffeine and its metabolites) and cotinine in human plasma.
Green analytical chemistry is a widely recognized concept that has led to the development of new analytical methods with reduced environmental impact and minimized analyst occupational exposure. This article presents the most recent progress in the development of greener sample preparation and chromatographic separation techniques.
In sample preparation, what does "high-throughput" really mean?
This article discusses the benef ts of using automated dispersive solid-phase extraction (dSPE) rather than standard SPE in urine analysis.

In this issue – I hope to outline some 'small bolts' that are commonly ignored in everyday chromatography and mass spectrometry - instrument settings that I have to come call 'lock and leave' parameters. We can generate data without changing them or paying them any attention, but how much better could our data be if we bothered to optimise them.
A program was formulated to help educate public opinion leaders on the fundamentals of unconventional natural gas and oil extraction, to convey the current state of research on the topic, and to disseminate and discuss prospective regulations that have been formulated over the past two to three years.
A new study published in the Journal of Chromatography A presents metabolite profiling of tea (Camella sinensis) harvested from the Bulang Mountains in Yunnan, China, using multidimensional gas chromatography–mass spectrometry (GC×GC–MS) to determine the impact of seasonal changes.
Scientists at the Norwegian Defence Research Establishment (Kjeller, Norway) are working in collaboration with the University of Oslo (Oslo, Norway) to develop new methods to detect the illicit use of nerve agents. In a recent study published in the journal Analytical Chemistry, the team presented a novel method for the quantification of nerve agent metabolites in human serum and urine by combining salting-out assisted liquid–liquid extraction (SALLE) and on-line solid-phase extraction–liquid chromatography–tandem mass spectrometry (SPE–LC–MS–MS).
A new study published in the journal Analytical Chemistry presents a drug metabolism strategy based on microsome mesoporous organosilica nanoreactors coupled with high performance liquid chromatography–mass spectrometry (HPLC–MS) to screen for potential drug toxicity.
The 3rd African Liquid Chromatography Workshop was held on 6–10 October 2014 in Nairobi, Kenya, at the ChromAfrica Training Centre.
LCGC Magazine is pleased to announce the addition of Douglas E. Raynie to its editorial advisory board.
In this new e-book, leading experts present the latest analytical tools for characterizing biopharmaceuticals, including chromatographic methods, mass spectrometry methods, and focused methods for analyzing carbohydrates on therapeutic glycoproteins.
