TSKgel™ CM-2SW columns are packed with 5 micron, high efficiency, spherical silica beads which are surface modified with a weak cation exchanger. They are used for the separation and analysis of small proteins, peptides, and other biologically active molecules. They have a smaller pore size than the TSKgel™ CM-3SW columns.
CYCLOBOND™ I 2000 is bonded with beta-cyclodextrin by a patented process to produce a stable matrix with the cyclodextrin arranged in such a way as to retain its most valuable property of forming inclusion complexes.
Packed with rigid, porous, polymer beads which show minimal shrinkage or swelling in different solvent systems. Used for the separation of polymers that are soluble in polar organic solvents. Exclusion Limit (DMF): Polyethylene Oxide 400,000 Da.
Available in a variety of stationary phases that function in normal and/or reverse phase. MilliporeSigma™ LiChroCART™ HPLC Cartridge, 250-2 comes with customized packing (please specify packing material) and is 250mmL x 2mmI.D.
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.
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.
