LiChrospher? CN has polar and hydrophobic properties, thus can be used as less polar alternative to LiChrospher? Si 60 in normal phase applications or as less hydrophobic alternative to LiChrospher? RP-8 in reversed phase applications. This sorbent is packed into a LiChroCART? 125-4 HPLC cartridge. The connection to the HPLC system is being accomplished by use of the manu-CART? NT cartrige holder (1.51486).
