Novel Selectivity For Tough Separations
Think high performance‚ enhanced retention‚ and the ability to go where a traditional C18 can’t. The Kinetex Biphenyl offers the high performance benefits of a core-shell particle with a unique stationary phase capable of becoming the go-to selectivity for reversed phase method development. Use Kinetex Biphenyl columns to get enhanced retention‚ higher sensitivity‚ and overall better results; especially for aromatic compounds.

Increased Separation of Aromatic Compounds Using a Biphenyl Phase
The elution order of analytes can change depending upon the predominate selectivity characteristics of a HPLC or UHPLC column and the utilized mobile phase. Therefore, by altering the stationary phase or mobile phase conditions, we can observe a unique elution order and extend retention of more polar analytes.
