AU140: The Determination of Iodide in Urine

Instrument Type: IC

In this Application Update, ion chromatography coupled with pulsed amperometric detection is used to determine iodide in urine. This method is specific, sensitive, and rapid. Sample preparation involves removal of urine components with molecular weights greater than 10,000 daltons, sample dilution, and treatment with a polymeric, reversed-phase cartridge (OnGuard™-RP).
