| Zorbax Poroshell columns are ideal for fast separations of proteins and peptides. Poroshell columns use a unique particle made with a thin layer of porous silica on a solid core of silica. This reduces the diffusion distance for molecules making practical rapid HPLC separations of peptides and proteins up to 500-1’000 kDa. Poroshell columns grafted with Stable Bond 300Å materials are exceptionally stable with TFA and formic acid containing mobile phases. Poroshell 300Extend-C18 can be use from pH 2 to 11.5. | ||
