EC HPLC column (analytical), NUCLEODUR 100-5 NH2-RP, 5 µm, 250x2 mm 548-3352 weakly acid cation exchanger (WCX)This HPLC column is packed with polar aminopropyl modification, based on high purity NUCLEODUR silica gel. This HPLC phase is able to generate a clearly recognizable different retention behavior compared to purely alkyl functionalized surface modifications. Besides cyano modifications, amino modifications belong to the most frequently used polar silica phases. Amino phases can be run in the RP mode using aqueous organic eluent mixtures as well as in
