LCGC: A Hydrophilic Interaction Chromatography Method for the Purity Analysis of Cytosine
LCGC, Vol 26, No 7: pp 632-642 (July 2008)
Mark Strege, Charles Durant, John Boettinger, and Michael Fogarty

A HILIC method (Hydrophilic Interaction Chromatography) was developed using a TSKgel Amide-80 column for the determination of cytosine purity. The HPLC system was equipped with electrospray ionization mass spectrometry detection for confirmation of the identity of selected related impurities.

New from the Leaders in Bioseparation...

Available now! The TSK-GEL STAT columns feature high performance IEC separations when you need answers fast. TSK-GEL STAT columns are applicable to a broad range of applications in research and quality control, such as:

v the monitoring of PEGylation reactions,

v the analysis of plasmids or DNA fragments.

v the separation of monoclonal antibody variants & aggregates, drug candidates and siRNA

Product Overviews

PO21: Toyopearl GigaCap CM-650M

Toyopearl GigaCap CM-650M is the second cation exchange resin in the Toyopearl GigaCap family, optimized for high throughput purification of IgG. Its base bead is Toyopearl HW-65C which has a particle size range of 50-100μm. This particle size range has outstanding pressure flow characteristics for high throughput IgG purification

PO22: TSK-GEL SP-STAT and TSK-GEL CM-STAT columns

TSK-GEL SP-STAT and TSK-GEL CM-STAT cation exchange columns allow fast equilibration and analysis, as well as isolation, of complex biomolecules. These columns offer very efficient chromatography for high as well as low MW solutes - made possible by novel bonding chemistry and the absence of micro-pores.
