Buffer salts and metals from the HPLC system become imbedded on the surface of the piston seal and gradually wear the surface of the piston rod. Worn regions on the rod will quickly destroy the pump seals. In turn, the seal material gets trapped on the frit at the head of the column, which leads to…
