Presto
Presto FF-C18 are octadecyl-modified, silica-based (U)HPLC columns, manufactured by Imtakt™. The base material consist of non-porous, spherical silica-particles with 2 µm particle size. Compared to fully porous phases, Presto columns show less band broadening as mass transfer effects are reduced. The columns show very high efficiencies and are well suited for the analysis of large molecules, e.g. polymers, surfactants, proteins or even DNA.
