ZIC®-cHILIC is based on the same technology platform as ZIC®-HILIC, but has a different functional group and an improved manufacturing procedure. The different charge orientation of the zwitterionic functional group leads to a different – and complementary – selectivity for polar hydrophilic compounds. This selectivity is especially beneficial for hydrophilic compounds that are negatively charged, positively charged, zwitterionic or neutral, for example, organic acids, amino acids, metabolites, aminoglycosides and nucleotides.

In general, ion exchangers consist of a cross-linked polymer matrix with a uniform distribution of fixed ionic groups sited throughout the resin structure. These must be balanced by a similar number of ions of the opposite charge, (counter ions) to maintain electrical neutrality. Cation exchangers therefore, exchange and enrich only cations, anion exchangers only anions. In contrast adsorber resins have a non ionic, but depending on the structure, a somewhat polar character, and don't adsorb stoichiometrically both: anions, cations, as well as uncharged compounds.
