SampliQ SPE 

SampliQ Diol SPE products area based on irregular, silica gel (silica) particles. This polar, bonded sorbent can exhibit both polar and weak non-polar interactions, depending on the cartridge preparation and sample matrix. While, with appropriate cartridge conditioning, it can be used as a non-polar sorbent to extract relatively non-polar molecules from aqueous samples, it is more frequently used to extract polar molecules from relatively non-polar solvents using hydrogen bonding interactions.
