Formerly made by Beckman Coulter, Ultrasphere still has high reputation

The Ultrasphere C18-IP (ion pair) phase was designed especially for ion pair reversed-phase HPLC. In general, the use of ion pairing reagents can reduce column lifetime. This phase is a C18 bonded phase, with substantially increased end capping to allow for maximum coverage which extends column lifetime, compared with the standard Ultrasphere ODS, in ion pair type applications.
