Obelisc Mixed-Mode HPLC Columns from SiELC

Obelisc HPLC columns from SiELC are the first commercially available columns with Liquid Separation Cell technology ( LiSC ). LiSC technology is based on a new chemical modification of the silica gel pores that creates a liquid separation cell with its own charge characteristics, ionic strength, and hydrophobic properties. Like living cells which exist in equilibrium with the outside environment, liquid separation cells exist in constant equilibrium with the mobile phase. Two columns based on LiSC technology, Obelisc R and Obelisc N, separate polar and non-polar compounds using multiple separation mechanisms.
