Pinnacle DB Biphenyl HPLC Column 1.9µm, 100 x 2.1 mm

Ruggedness and reproducibility are guaranteed during the control of every step in the process, from base silica to bonded phase to final packed column. The silica particles are classified and selected to give an exceptionally tight distribution around 1.9µm, while eliminating <1µm particles that can contribute to a poorly packed bed. Highly base-deactivated Pinnacle™ DB stationary phases are an excellent choice when analyzing a wide range of compounds, from acidic to basic.
