Partisil ODS is a low carbon load C18 phase, with intentionally unbonded surface silanols adding to the selectivity.Partisil ODS2 is a high carbon load C18 bonded silica phase which makes it the most non-polar and, therefore, the most retentive of the Partisil reversed-phase columns. The high sample load capacity is suitable for preparative work.Partisil ODS3 is an intermediate carbon load C18 phase used for pharmaceutical, natural products, food, biological and environmental pollutants applications.Partisil 10 ODS3 is similar to Waters µBondapak.Partisil C8 is recommended for ion-pair chromatography.Partisil PAC is a Polar Amino Cyano bonded phase with secondary amine groups for good thermal and chemical stability. Fast equilibration enables multiple separation mechanisms, including adsorption, reversed-phase and weak anion-exchange, to be used. The phase is particularly suitable for carbohydrate separations.Partisil SAX is a strong anion-exchange phase based on quaternary ammonium groups. It is stable over the pH range 1.5 to 7.5. Typical applications include nucleic acids, organic acids and inorganic anions.Partisil SCX is a strong cation-exchange phase based on benzenesulphonic acid groups and is stable over the pH range 1.5 to 7.0. Suitable applicationsinclude nucleosides, amino acids, polyamines, drugs and other cationic species.
