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.
SUPELCOSIL™ LC-DB phases are specially deactivated for basic compounds. These columns provide less retention, better peak shape, and higher efficiency for organic bases than can be obtained on conventional reversed-phase columns.
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 2,000 Da.
Ascentis™ Express OH5 columns can be used for traditional normal phase separations using non-polar, totally organic mobile phases or for aqueous normal phase chromatography with the typical mobile phases for hydrophilic interactive liquid chromatography (HILIC) of basic, acidic, zwitterionic, or neutral compounds.
TSKgel™ ODS-120T columns contain 150 Å pore size silica particles. The exclusion limit of 10,000 Da makes TSKgel™ ODS-120T columns a good choice for the reversed phase chromatography of peptides, small proteins, and small molecular weight compounds in organic and environmental samples.
TSKgel G3000HHR Columns are packed with rigid, porous, polymer beads. They are from a class of columns used for the non-aqueous separation of oligomers and polymers less than 60,000 Da.
TSKgel G2000HXL Columns are packed with rigid, porous, polymer beads. They are applied to the non-aqueous separation of polymers with molecular weights of less than 10,000 Da.
Ascentis™ Express Peptide ES-C18 columns are specifically engineered to separate higher molecular weight compounds such as peptides and small proteins.
Available in a variety of stationary phases that function in normal and/or reverse phase. MilliporeSigma™ LiChroCART™ HPLC Cartridge, 250-3 comes with customized packing (please specify packing material) and is 250mmL x 3mmI.D.
