Waters Spherisorb Anion Exchange Prep Column 5µm 20 x 250mm, Box of 1

The Waters Spherisorb SAX HPLC column 250x20mm, 5µm, is built on spherical silica and carries strong anion-exchange groups. In anion-exchange chromatography the Waters Spherisorb SAX is used and separates analytes via charge-dependent interactions. The strong anion-exchange functionality enables robust retention of anionic compounds. The Waters Spherisorb SAX is used, among other things, for organic acids, nucleotides, anionic drugs and ionic impurities.

Features and Benefits

• Robust 80-Å silica
• Particle sizes of 3, 5, and 10 µm
• Phases for RP, NP, and ion exchange
• ODS1 and ODS2 with different ligand densities
• Analytical and preparative formats

Additional Information

The Spherisorb series is based on mechanically robust silica with a pore size of 80 Å and is available in several particle sizes. ODS1 has a lower ligand density and lower carbon loading, while ODS2 offers a more densely packed, end-capped C18 surface. The series is complemented by short alkyl chains, cyano, phenyl, amino, and silica phases, as well as strong anion- and cation-exchange phases. This allows for the coverage of a wide range of classical HPLC methods using a silica base that is consistent across the product family.
