Ultrahigh-Efficiency Protein Separations with Submicrometer Silica Using Slip Flow
October 1st 2012Professor Mary Wirth and graduate students Bingchuan Wei and Benjamin Rogers from Purdue University demonstrate a quantum leap in protein column efficiency. Using colloidal silica particles of submicrometer diameters (470 nm), they obtained plate heights that were as much as 15-fold lower than the theoretical limit for Hagen-Poiseuille flow.
AB SCIEX launch new biologics initiative
September 21st 2012At the International Mass Spectrometry Conference (IMSC) in Japan, AB Sciex (Massachusetts, USA) announced the introduction of an initiative targeted at the development of biologics, a rapidly growing research area within the field of drug discovery.
TitrIC pro - multi-ion analysis by automated titration and ion chromatography
September 21st 2012TitrIC pro combines titration, ion chromatography and direct measurement in a single analytical system. TitrIC pro is operated by MagIC Net, the sophisticated Metrohm standard software for ion chromatography.
50 Billion Photons Can't be Wrong!
September 21st 2012Based 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.
Turning the Spotlight on Capillary Electrophoresis.
September 20th 2012Capillary electrophoresis (CE) provides a number of advantages for analysts, including high separation efficiency, short analysis times, low waste generation and a diverse range of applications. Participants in this forum are Bill Ciccone, Microsolv; Martin Greiner, Agilent Technologies; and Mark Lies, Beckman Coulter Life Sciences.
