A team of scientists has performed a series of analyses on three sets of Spanish red wine to see how price affects aroma chemical composition.

HFL Sport Science (HFL), a part of the LGC Group (Teddington, Middlesex, UK) and one of the world’s largest sports drug surveillance laboratories, is preparing for its role testing the horses competing in equestrian events at the Olympic and Paralympic Games.

We note here the passing of pioneering American gas chromatographer Walter G. Jennings on July 5, 2012. Walt, as he preferred, died peacefully at home surrounded by family. He was 90 years old.

Traditionally GPC/SEC is a slow technique. A typical, non-optimized GPC/SEC run with 3 analytical columns and a precolumn needs about 45 to 60 min to be completed. This limits the number of samples that can be analysed.

An excerpt from LCGC's e-learning tutorial on HPLC for reversed-phase separations at Chromacademy.com.

A pioneer in high performance liquid chromatography reflects on his career and how "enlightened trial-and-error" can reduce the effort involved in method development.

This article provides examples of the use of SLE, demonstrates some of its advantages and provides commercial sources for SLE products.

Problems with retention-time drift, temperature control, and broad peaks from a new column are discussed.

Milestone events, like LCGC's celebration of 30 years of covering separation science, always prompt reflection on the past and consideration of what the future might hold. Thus, for this 30th anniversary issue, we turned to the experts in five key areas of our coverage: sample preparation, gas chromatography (GC) columns, GC instrumentation, liquid chromatography (LC) columns, and LC instrumentation. Now, in the special group of five articles in this issue, we bring you their perspectives on the state of the art: what the most important recent advances have been, where things stand today, and where the field is likely to go next.

LCGC's global online presence is an ever-growing aspect of this publication as we strive to bring our readers the knowledge they need in a timely manner.

An alternative approach to liquid–liquid extraction is explored.

Ion-exchange chromatography (IEC) is based on the different affinities of analyte and eluent counterions for the oppositely charged ionic functional groups on the stationary-phase surface of an exchange resin. Depending on the charge of the surface electrostatic groups, the resin could be either an anion exchanger (positively charged stationary phase) or a cation exchanger (negatively charged stationary phase).

Event news

The statistical nature of experiments leads to the fact that standard deviation (SD) of replicate analysis is not constant but a number with some variability: a standard deviation has its own standard deviation. As a consequence, a SD calculated from three experiments is not rugged and even SDs from ten experiments show a great variability. Analysts should be aware that with 100 or more the results have low scatter
