Gel permeation chromatography/size exclusion chromatography
17 September, 2009 byViscotek has published application notes illustrating the extended capabilities of gel permeation chromatography/size exclusion chromatography (GPC/SEC) using the photodiode array (PDA) detector for the TDAMax system. Now available on the Viscotek website, these application notes illustrate how the detection technology brings greater flexibility to multi-component characterisation and analysis in fields from polymer science to biopharmaceuticals. The application notes describe ‘Conjugated polymer analysis by GPC-PDA’ and ‘Polymer blend analysis by GPC-PDA’ respectively. Both are freely downloadable at http://www.viscotek.com/gpcpda.htm.

The software driver comes standard with all new Corona detectors. The driver can also be used with ESA’s Corona CAD and Corona Plus detectors. Existing users can download a copy by visiting: http://www.esainc.com/services/software_downloads/empower_driver.
Size exclusion chromatography solution
09 June, 2009 byThe Prosec 300S is a size exclusion chromatography column designed for the accurate and precise analysis of globular proteins in the pharmaceutical and bioscience industries.
Liquid chromatography system
09 June, 2009 byThe Agilent 1290 Infinity liquid chromatography system has been designed to deliver greater power, speed and sensitivity for enhanced performance in the high-end ultra high performance liquid chromatography (UHPLC) market.
Glycan characterisation
09 June, 2009 byWaters has released the UltraPerformance LC (UPLCÂ) analytical solution for the characterisation of 2-AB labelled glycans from glycoproteins. The UPLC solution combines the Acquity UPLC BEH Glycan Columns with the Acquity UPLC System equipped with fluorescence detection. Current FDA regulations require that firms developing and manufacturing therapeutic proteins are able to accurately characterise the glycans attached to those proteins to ensure the efficacy and safety of a biopharmaceutical product.
Ascentis Express HPLC columns
09 June, 2009The increased efficiency of the Fused-Core particle in the Ascentis Express HPLC columns enables users to use shorter columns and reduce acetonitrile use by up to 70%.
