HPLC Guard Cartridges Spursil C18-EP, 100 Å, 10 µm, 21.2 x 10 mm, 2 pc/PAK

Spursil polar-modified phases are based on ultra high-purity silica and novel polar modification technology. The unique bonded phases maximize polar retention and selectivity, while virtually eliminating silanol activity. The resulting polar-modified packing material contains a surface which is easily "wetted" with polar eluents and can run in highly aqueous conditions.
