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.

Part 1 of evidence to demystify HPLC and UHPLC column myths

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.

Based on Wyatt Technology’s family of multi-angle light scattering detectors, the new DAWN HELEOS-II boasts 18-angles of detection for the greatest sensitivity for absolute molecular weight and size determinations of polymers and biopolymers in solution. It may be connected in series to any chromatographic system in order to determine absolute molar masses without the use of reference standards or column calibration.

Chromatography can be approximated by a series of equilibrium events between the mobile phase and stationary phase. Here, LCGC Blog editor Kevin Schug discusses an exceptional spreadsheet macro written by an undergraduate researcher that helps users visualize the development of chromatographic separations.

An interview with Norman Dovichi, winner of the 2013 ANACHEM Award. This interview is part of the 2013 podcast series presented in collaboration with the Federation of Analytical Chemistry and Spectroscopy Societies (FACSS), in connection with SciX 2013, the federation?s North American conference.

Comprehensive two-dimensional gas chromatography (GCXC) has been performed to identify the origins of a mysterious oil sheen in the Gulf of Mexico, first reported in September 2012. The results have been published in the journal Environmental Science and Technology1 by researchers from the University of California (California, USA) and the Wood Hole Oceanographic Institute (WHOI) (Massachusetts, USA).

Fava beans are a good source of polyphenols and are located in different parts of the plant. Phenolic compounds are thought to contribute to the overall antioxidant activities of plant foods. However, there is a lack of information on the phenolic composition of the seeds (beans) of some edible varieties. This has led a team of researchers based in Chile and Spain to use high performance liquid chromatography (HPLC) to identify the composition of a variety of immature fava seeds.1
