Ruggedness and reproducibility are guaranteed, as we
control every step in the process, from base silica to
bonded phase to final packed column. The silica parti-
cles 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. To optimize
your ultra high pressure HPLC methods, reach for
Restek small particleHPLC columns!
