Supelcosil™ SAX1 HPLC Column, 5 µm particle size, L x I.D. 25 cm x 4 mm

The Supelcosil SAX1 HPLC column 250x4.0mm, 5µm, is a strong anion‑exchange silica phase. The Supelcosil SAX1 is used for ionic separations in which acidic or anionic compounds are retained by electrostatic interactions. Applications of the Supelcosil SAX1 are organic acids, nucleotides, anionic active substances, counter‑ion analysis and ionic impurities.

Features and Benefits

• Classic silica HPLC platform
• Many USP-compliant modifications
• RP, NP, ion-exchange, and specialty phases
• Proven for routine methods
• Compatible Supelguard cartridges available

Additional Information

Supelcosil columns are based on porous, spherical silica and cover a very wide range of classic HPLC selectivities. In addition to C18, C8, cyano, amino, diol, and silica phases, base-deactivated DB variants, ionic modifications, and application-specific phases such as LC-PAH or Hisep are available. This makes Supelcosil particularly suitable for established methods, USP-compliant applications, and routine analysis where a known stationary phase needs to be reproducibly replicated.
