Presto is a highly uniform ultra-pure base silica derivatised with C18. Non Porous RP materials have lower carbon content. Their lack of pores  this makes them ideal for separating all kinds of Bio and synthetic polymers. The lack of pores leads to better mass transfer and improved efficiency, better recovery of solute and much better peak shape due to low dispersion. Presto ODS is different from conventional reverse phase materials and is ideal for proteins, peptides, polysaccharides and large nucleic acids as well as both hydrophillic and hydrophobic synthetic polymers. Presto is available packed into a wide range of column dimensions from 0.05mm ID to 20mm and from 250mm length to 3cm. As well as having enormous peak capacity for peptides, Presto can be used for very difficult polymer separations, such as hyaluronic acid.
