OroSym C18 column series are bonded to the maximum density to have the highest hydrophobicity and thus the lowest polarity. High C18 moieties result in the lowest interaction with analytes, with silanol, and demonstrate high stability at high pH and the broadest pH range. OroSym columns also demonstrate cleaner separation power for isomers, with a near perfect symmetry for basic, acidic and neutral compounds.
