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
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.

Since its' founding in 1997, WITec has established itself as a market leader in the field of nano-analytical microscope systems (Raman, AFM, SNOM). As reflected in WITec?s maxim "Focus Innovations", our success is based on constantly introducing new technologies and a commitment to maintaining customer satisfaction through high-quality, flexible and innovative products.
Split/splitless injectors typically vaporise a sample dissolved in a suitable organic solvent under increased temperature. The sample vapours are entrained into the carrier gas flow inside a "liner" or "sleeve" within the inlet and from there pass into the column or out of the inlet via "split" line / valve. Splitless injection is used to perform an "on-instrument" dilution and the relative amounts of sample which enter the column or discarded to waste via the split line are adjusted using the relative carrier and split flow rate ratio.

Let you quickly resolve and identify amino acid modifications in primary structure. These advanced biocolumns feature a 120A pore size with superficially porous 2.7 μm particles. They are specially tested with a challenging peptides mix to ensure reliable peptide mapping performance. In addition, AdvanceBio Peptide Mapping columns deliver exceptional resolution and speed for UHPLC, and excellent results for conventional HPLC too.
Where do all those extra peaks come from?
A new candidate biomarker of sugar and sugar-sweetened beverage (SSB) intake has been proposed in a recent study published in the Journal of Nutrition.1 The study presents the carbon isotope ratio of alanine as a new biomarker for use in studies monitoring dietary sugar intake
J. Calvin Giddings provided one of the most practical discussions of the advantages of temperature programming in GC over isothermal analysis back in 1962. Here, Kevin Schug describes some of the salient points of that discussion and how they still apply today.
HPLC method development is an arduous process requiring considerable experience and scientific judgement. In this article, a roadmap for rapid HPLC method development using a three-pronged approach is presented.
Sigma-Aldrich (Missouri, USA) has announced that it has partnered with The Scripps Research Institute (TSRI) (California, USA) to speed up access to discoveries by TSRI scientists to synthesize and analyze potential drugs. The partnership is the first to be formed between an academic institution and a reagents company.
