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.
Use a strong anion-exchange column with the Thermo Scientific™ DNASwift™ SAX-1S Oligonucleotide Column that provides exceptionally high resolution for the purification of oligonucleotides.
The pentafluorophenylpropyl stationary phase of Ascentis Express F5 provides a stable reversed phase packing with electron-deficient phenyl rings due to the presence of electronegative fluorines.
The TSKgel™ SuperOligoPW column is designed for the determination of molecular mass of aqueous oligomers, particularly oligosaccharides, and low molecular weight aqueous polymers.
Thermo Scientific™ POROS™ CaptureSelect™ KappaXL Affinity HPLC columns incorporate the advantages of high-speed POROS chromatography resins with the unique selectivity of CaptureSelect affinity ligands.
Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column.
TSKgel SuperHZ2000 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 10,000 Da.
TSKgel SuperHZ2500 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 20,000 Da.
TSKgel SuperHZ3000 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 60,000 Da.
Packed with rigid, porous polymer beads which show minimal shrinkage or swelling in different solvent systems. Columns are best used for the separation of polymers that are soluble in polar organic solvents.
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).
