We Recommend Gemini HPLC for Robust Method Development across all pH Extremes
Columbus columns are designed to provide robust and reproducible separations for traditional HPLC methods. Dense endcapping lend to the stability of Columbus columns since the silica surface is shielded from unwanted silanol activity.
