Hydrophobic C18 phase with distinct polar selectivity for better retention of early eluting substances. This UHPLC phase is made of high purity NUCLEODUR® silica gel and shows excellent performance under highly aqueous conditions. Due to low bleeding characteristics these columns are suitable for LC/MS. This stationary phase is used for overall sophisticated analytical separations, especially for polar compounds.
Delivery incl. 1x analytical HPLC column, instruction leaflet, certificate of analysis.
