Lichrolut® columns are designed for reliable and rapid solid phase extraction. This is achieved by using strong but reversible interactions between the analyte and the surface of the stationary phase. A variety of surface modifications allow non-polar extractions (Lichrolut® RP18 and RP18e), polar extractions (Lichrolut® Si and Lichrolut® CN), Cation Exchange extraction (Lichrolut® SCX), mixed mode extraction (Lichrolut® TSC) and non-polar extractions on a polymer phase (Lichrolut® EN) which is especially well suited for the extraction of pesticdes and phenols in water or drugs in body fluids.
