The Cadenza CL-C18 with 3 µm particles and Cadenza 5CL-C18 with 5 µm particles are silanol-regulated C18 columns. Controlled, partial endcapping exposes residual silanols and offers unique selectivity. Due to its partial endcapping, the Cadenza CL-C18 opens a new world of separation possibilities.
Almost all recent ODS columns have complete endcapping, however, complete endcapping makes some separations impossible. Conversely, ODS columns without any endcapping provide poor elution characteristics due to the influence of silanol. Our new Cadenza CL-C18 with partial encapping uniquely optimizes the remaining silanol.
Features
- Cadenza CL-C18 has 3 µm particles
- Cadenza 5CL-C18 has 5 µm particles
- Silanol-regulated ODS phase provides additional selectivity options for ionic compounds
- Cadenza CL-C18 has the same base silica and ODS ligand density Cadenza CD-C18. They differ only in the amount of residual silanols on the silica surface.
- Neutral compounds with oxygen-rich structures have improved separation on Cadenza CL-C18 due to the effect of the silanols
- Three versions of CL-C18: 250 bar, 500 bar (HT hardware) and 1000 bar (UP hardware)
