Bond Elut™ PRS is a strong cation exchange sorbent that is also relatively high in polarity. With no appreciable degree of hydrophobicity, in non-polar solvents, PRS is capable of polar and hydrogen bonding interactions. Due to the very low pKa of PRS, a high ionic strength eluent must be used, and so the use of PRS is recommended for weaker cationic species such as pyridinium compounds.

Supplier: Thermo Fisher Scientific

These columns result in a multimode separation mechanism including hydrophobic, anion-exchange and cation-exclusion interactions. Consequently, retention of basic, neutral and acidic molecules can be either independently or concurrently adjusted by changing ionic strength, pH and organic solvent content in the mobile phase.

The PRP-X100 is a polymeric column packing for separation of inorganic and organic anions from 10 to 500 ppm. These columns can be used to separate ions at concentrations from 1 to 1000 ppm without suppression or elaborate preconcentration techniques. The highly inert polymeric support resists chemical attack from organic solvents and aqueous buffers (0 - 100% aqueous or organic; pH 1 to 13), effectively lengthening column life.
