Hamilton HPLC Guard Column PRP-1, 12-20 μm, 4.6 x 33 mm

PRP-1 columns have inherent reversed-phase separation qualities that eliminate the requirement for a stationary phase coating. Hydrolysis of the stationary phase coating is often the limiting factor in column lifetime, so the lack of coating on the PRP-1 resin extends the longevity of the column. PRP-1 also have exceptional sample recovery (≥ 95%).
