Hi-PuritTM PS/DVB a highly cross-linked polystyrene-divinyl benzene copolymer sorbent that allows for rapid adsorption and separation of hydrophobic substsances, such as phenot, surfactants, non-B pyridine, antibiotics, amino acids and peptides, etc.Ideal for the extraction of popular analytes that are not adequately retained on a C18 or C8 sorbent is useful for screening applications where a board range of analytes is to be extracted.Equivalent to Agilent Bond Elute LMS, Bond Elute PPI .Wider selectivity range provides more eluent optionsPolar or non-polar depending on matrix or solvent Typically used when dealing with very strong cationic [high pKa] compounds that may be irreversibly retained on strong cation exchangers
