In this instalment, John Hinshaw compares the GC separation process to a long-distance run through a long corridor with some unique properties. The runners are separated in various ways.

The American Chemical Society (ACS) has named Daniel W. Armstrong, professor of chemistry and biochemistry at the University of Texas (UT) Arlington, to its 2013 Class of Fellows.

The reasons that make HPLC so ubiquitous; the fundamentals on how we conduct HPLC separations; and a few opportunities with far-reaching impacts in life sciences for separation scientists are discussed in this article.

Understanding the chemistry behind gas chromatography (GC) separations can lead to faster problem identification and improved troubleshooting.

In contrast to isocratic separations, gradient elution can sometimes seem to be counter-intuitive. Yet with the proper perspective, the things we intuitively understand about isocratic methods apply in a similar manner to gradients.

Material identification is a common need in many industries, most notably for pharmaceutical manufacturing where the United States Pharmacopeial Convention (USP) defines many identification tests.

This article describes the GC–MS and LC–MS screening methods developed for the analysis of both low-volume water samples and extracts obtained from various designs of passive samplers.

Experts in the food industry are always searching for natural sources of bioactive compounds to develop products that enhance athletic performance. A new study has suggested that drinking watermelon juice may alleviate muscle ache experienced by many athletes, and non-athletes, following a period of exercise. The study published in the Journal of Agricultural and Food Chemistry showed that naturally high levels of L-citrulline in watermelon juice may be more effective than pharmacological supplements.

Scientists from the University of Bradford (Bradford, UK) have utilized liquid chromatography?tandem mass spectrometry (LC-MS-MS) to gain further insight into the child sacrifice practices of the Inca people.1 Their findings indicate the use of alcohol and cocaine (COC) as a method of victim sedation.
