Part 1 of evidence to demystify HPLC and UHPLC column myths

Ultra-high sensitivity, expanded flexibility, increased stability and robustness - the Nexera X2 UHPLC system targets routine analysis and applications in highly regulated envi-ronments demanding complex system setups.

Fasha (Farshad) Mahjoor, CEO of Phenomenex (California, USA), has been elected to the American Red Cross Los Angeles Region Board of Directors. The appointment follows the award of the Ellis Island Medal of Honor to Mahjoor earlier this year, for building a socially responsible international business and for his humanitarian efforts in the USA and worldwide.

Waters Corporation (Massachusetts, USA) has acquired the UK-based company Nonlinear Dynamics Ltd (Newcastle upon Tyne, UK). The acquisition marks the goal of Waters to advance the rate of discovery in proteomics, metabolomics, and lipidomics.

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

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.

JJ Symposium

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.
