ES Industries research and development efforts have yielded a new HPLC column - Chromegabond WR- Biphenyl. This development has elevated the Chromegabond WR-Biphenyl HPLC stationary phase to the next level of selective separation performance with the introduction of this new HPLC column. Chromegabond WR-Biphenyl is a truly unique stationary phase with properties significantly different than ODS phases.
