LiChrospher? RP-8 is a reliable and versatile traditionally produced spherical silica gel carrier with C-8 reversed phase properties. It is well suited for the separation of neutral, acidic and weak basic compounds. This sorbent is packed into a LiChroCART? 100-4.6 HPLC cartridge. The connection to the HPLC system is being accomplished by use of the manu-CART? NT cartrige holder (1.51486).
