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.
Ideal for analysis of hydroxy acids, like lactic, malic, tartaric and mandelic acids, amino acids, other amines and bi-functional racemates, like amino alcohols.
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.
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.
ChromegaChiral™ CCO is a polysaccharide coated chiral stationary phase and columns which are produced using a unique production process of coating the proven chiral selector, tris-(3,5-di-methylphenyl) carbamoyl cellulose on high purity, high performance silica.
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).
Ascentis™ Express PCS-C18 columns are specifically engineered to provide efficient separation of basic, acidic, or neutral compounds under low ionic strength (formic acid) mobile phase conditions.
Ascentis™ Express PAH provides a stable, reversed-phase packing that can be used for analysis of acids, bases, and zwitterionic compounds, but has been specifically designed for the separation of polycyclic aromatic hydrocarbons.
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.
