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.
Ascentis™ Express RP-Amide can be used for basic, acidic, or neutral compounds with orthogonal selectivity from C18 or C8. The polar-embedded Ascentis™ Express 5 μm RP-Amide columns are compatible with 100% aqueous mobile phases without suffering from 'phase collapse'.
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.
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 60,000 Da.
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 > 4 x 107 Da.
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.
Porous-layer open-tubular (PLOT) columns are a powerful tool used in gas chromatography for analysis of fixed gases, light hydrocarbons and volatile solvents. They are mostly preferred over traditional columns.
The Ascentis™ Phenyl provides superior separations in reversed-phase mode including 100% aqueous conditions. It may also be used in HILIC/ANP (aqueous normal phase) mode and shows low UV/MS bleed for gradient applications.
