HPLC Guard Cartridges Nucleosil 100 SA, 5.0 µm, 2 x 10 mm, 5pc/PAK

Nucleosil is one of the first standard silica gel phases for HPLC. It consists of a completely porous spherical silica gel with a very pure and uniform SiO2 structure. It is considered an extremely reliable choice for analytical and preparative routine use. The pore width can vary from 50 to 4000 Å and available particle sizes are 3 μm, 5 μm, 7 μm and 10 μm. The SA phase is a benzene sulfonic acid-modified SiO2 structure. This is a strongly acidic cation exchanger (SCX).
