Columns and cartridges for gas, ion, HPLC, low-pressure LC, and flash chromatography; includes pre-packed and open columns, packing, guard columns and accessories, and other supplies for flash chromatography.
TSKgel™ DEAE-3SW columns are packed with 10 μm porous spherical silica beads which are chemically modified with a weak anion exchanger. They are used for the separation and analysis of proteins, peptides, nucleotides, nucleosides and other biologically active molecules.
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).
LiChrospher™ RP-8 HPLC Column is a traditionally produced spherical silica gel carrier with C-8 reversed-phase properties and is suitable for acidic, neutral and weakly basic compounds.
The Ascentis™ Si is a high loading capacity silica with excellent peak shape. The Ascentis™ Si performs in both normal-phase and HILIC/ANP (aqueous normal phase) mode.
Packed with 5 μm porous, spherical particles which are surface modified with a strong (sulfonic acid) cation exchanger in the hydrogen. Column is optimized for the separation and analysis of organic acids, saccharides, and alcohols.
Scale up to prep LC using Hypersil PREP C8 BDS HPLC columns which offers selectivity similar to C18 but with reduced retention in analytical and preparative scale.
Highly cross-linked polymethacrylate base material provides excellent stability in high pH buffer systems. Withstands rigorous cleaning with either acid or base, 125 Å pores allow for analysis of peptides up to 8,000 Da.
