The addition of extra detectors such as light scattering and intrinsic viscosity to a single-detector size-exclusion chromatography system or, better still, the use of an integrated multi-detector size-exclusion chromatography system can pay significant dividends in the breadth of sample information generated.

The health benefits of barley grain as a source of dietary fibre are well known. In the case of barley, as with most cereals, the phenolic compounds are concentrated in the bran, which until recently was removed during the milling process. Now food researchers are investigating the possibility of producing barley flours naturally enriched in bioactive compounds and have shown that the separation of different fractions of whole barley by pearling have resulted in the outermost fractions yielding the highest phenolic content.
Agilent Technologies will collaborate with Dr Shane Snyder ? an internationally recognized authority on water contamination from the University of Arizona?s Department of Chemical and Environmental Engineering ? and the university?s BIO5 Institute to develop new methods of detecting emerging contaminants in water, according to a company press release.
Acquired drug resistance (ADR) is a major problem when it comes to treating some forms of cancer and one that has been baffling cancer researchers for some time. Now a team at Moffitt Cancer Center in Tampa, Florida, USA are pioneering research using liquid chromatography multiple reaction monitoring (LC-MRM) to track the proteins involved in ADR. Ultimately this could assist in clinical decision-making for developing individualized patient treatments for multiple myeloma and other types of cancer. The research results are published in the October issue of Molecular and Cellular Proteomics.
