Regenerate™ SP
Together with SACHEM's protocols, these products will ensure reproducible results with displacement chromatography.
2.0M NaCl is often adequate to remove SP displacers.  However, for improved efficiency and performance we offer a variety of enhanced regeneration agents.

We offer a number of choices that vary by pH.  Choice of pH is based upon individual system requirements or personal preference.  Use 5-10 column volumes at an appropriate flow rate for your system.

Regenerate™ SP-N is a neutral regeneration agent (pH=7.0) for cation exchange columns. Regenerate™ SP-A is an acidic regeneration agent (pH=2.0) for cation exchange columns. Regenerate™ SP-B is a basic regeneration agent (pH=12.0) for cation exchange columns.

If you have no preference on pH, we recommend 8500 Regenerate™ SP-B.
