TSKgel Phenyl-5PW RP offers similiar selectivity to its hydrophobic interation counterpart TSKgel Phenyl-5PW, although a higher degree of cross-linking allows for increased stability in aqueous/organic mobile phase gradients. Provides an advantage over silica when high pH buffer systems are needed.
Analytical groups supporting biologic drug development require rapid, sensitive, and precise methods for protein quantitation from cell culture, fermentation harvests, or purification intermediates.
The bare silica stationary phase of Ascentis™ Express 5 μm HILIC provides a column that can be used for traditional normal phase separations using non-polar, totally organic mobile phases or for aqueous normal phase chromatography with the typical reversed-phase mobile phases for hydrophilic interactive liquid chromatography (HILIC) of basic, acidic, or neutral compounds.
Ascentis™ Express PCS-Phenyl-Hexyl columns are specifically engineered to provide efficient separation of basic, acidic, or neutral compounds under low ionic strength (formic acid) mobile phase conditions.
ChromegaChiral™ CCO is a polysaccharide coated chiral stationary phase and columns which are produced using a unique production process of coating the proven chiral selector, tris-(3,5-di-methylphenyl) carbamoyl cellulose on high purity, high performance silica.
TSKgel SuperHZ1000 Columns are packed with rigid, porous, polymer beads. They are used for the non-aqueous separation of solvent-soluble small molecules and oligomers less than 1,000 Da.
An excellent choice for pegylated proteins or glycosylated biomolecules. The fractionation range is applicable for globular protein samples up to 7 million Da.
Control interactions between the hardware and analytes. MilliporeSigma™ SeQuant™ ZIC™-HILIC (3.5μm, 100Å) PEEK Coated HPLC Column, 100-2.1 has an inert coating, a high-performance, zwitterionic stationary phase and a larger surface area
Thermo Scientific™ POROS™ Prepacked Strong Cation Exchange Column. POROS HS is a high capacity, strong cation exchange, High Performance Chromatography™ resins suitable for the separation and purification of biomolecules.
The LC-CN phase is often used as a substitute for silica because it offers the advantages of a bonded phase (such as quick equilibration, and less sensitivity to small changes of the water content in the mobile phase).
TSKgel™ SuperHZM-N Mixed-Bed Columns are packed with rigid, porous, polymer beads each having a varying mean pore diameter. They are used for the analysis of organic-soluble polymers with high molecular weights of less than 700,000 Da.
