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

Martin Giera and colleagues from the Center of Proteomics and Metabolomics (The Netherlands) have published a study in the Journal of Chromatography B1 evaluating different column chemistries for reversed-phase liquid chromatography (RP-LC) and hydrophilic interaction chromatography (HILIC) for fast urinary metabolic profiling.

Integral calibration with a broad standard is a fast, cost-effective, and easy-to-use calibration technique for quality control. This article explains more.

An automated liquid chromatography (LC) method with on-line enrichment was successfully developed for the analysis of eight chlorinated phenoxyacid herbicides in water.
