Nacalai Tesque COSMOSIL 3C18-AR-II Packed column, 120Å, 3 μm, 2.0 mm ID x 50 mm
COSMOSIL 5C18-AR-II is a polymeric type of C18 phase. It shows exceptional stability and long lifetime at low pH. This phase is recommended for the separations requiring acidic mobile phase conditions. The acidic resistance of COSMOSIL 5C18-AR-II is much improved compared with commercially available monomeric type octadecyl stationary phases. It retains high performance even in case of acidic mobile phases commonly used to separate acidic compounds and peptides. It also shows superior molecular shape selectivity to monomeric type C18 columns. Polymeric bonded type C18 (ODS) pH Range 1.5-7.5 approx. 17% Carbon Content Features strong acid resistance Suitable for acid compounds and peptidesShow more
