Three cationic polymers were used as electroosmotic flow and selectivity modifiers for simultaneous determination of inorganic anions and metal-4-(2-pyridylazo)resorcinolato (PAR) chelates. It was shown that the ability of polymers to associate with analytes decreased in the order: poly-(N-ethyl-4-vinylpyridinium bromide)>poly-(diallyldimethylammonium chloride)>Polybrene. CrO42- was chosen as a background electrolyte anion, because it enables indirect W detection of transparent analytes at 254 nm and do not affect the detection sensitivity of chelates at 490 nm. Rapid (4 min) separation of Co(II), Ni(II), and Fe(II)-PAR chelates and of 11 inorganic anions was demonstrated.
