Pre-packed columns, cartridges, and guard columns for separation of biomolecules and organic/inorganic analytes; includes normal/reversed phase HPLC, UHPLC, LC-MS, HILIC, mixed-mode, ion exchange, ligand exchange, and affinity column formats.
TSKgel™ G-Oligo-PW is designed for high resolution separations of aqueous nonionic and cationic oligomers, and oligosaccharides such as hydrolyzed cyclodextrins. Because of the presence of cationic groups on the gel matrix, this column is not suited for separating anionic polymers. The PEG and PEO calibration curve is identical to that of G2500PWxl.
Available in a variety of stationary phases that function in normal and/or reverse phase. MilliporeSigma™ Hibar™ HPLC Columns, 250-4 come with customized packing (please specify packing material) and are 250mmL x 4mmI.D.
A typical mobile phase used with normal-phase silica columns consists of a hydrocarbon solvent such as hexane or heptane, mixed with a relatively small percentage of more polar solvent.
Discovery™ BIO Wide Pore C5 was designed for the efficient and reliable separation of proteins and peptides, especially hydrophobic peptides, by RP- HPLC.
The unendcapped trifunctional C18 stationary phase of Ascentis™ Express PAH provides a stable, reversed-phase packing that can be used for analysis of acids, bases, and zwitterionic compounds, but has been specifically designed for the separation of polycyclic aromatic hydrocarbons.
TSKgel G5000HHR Columns are packed with rigid, porous, polymer beads. They are from a class of columns used for the non-aqueous separation of polymers with molecular weights less than 4,000,000 Da.
Scale up with Hypersil PREP C18 BDS preparative LC columns for routine applications and C18 retention with base deactivation for reduced silanol activity.
