The 100A or 300A pore sizes are available in 3, 5 or 10µm particle size. The wider pore size distribution is our Most Popular C4 phase and is used routinely for separation of small to medium size proteins, peptides, enzymes and other bio-separations due to its non-polar ligand.
For sensitive, bio-compatibility or for any compound that interacts with stainless-steel, use the metal free, stainless steel coated columns.
