TN62: Reducing Carbonate Interference in Anion Determinations with the Carbonate Removal Device (CRD): Trace Anions
DescriptionCarbonate can interfere with accurate quantification of adjoining anions, such as sulfate. Here we show the efficient removal of the carbonate peak from a trace analysis water sample using the Dionex CRD 200 device. In this example, a large volume (1000 uL) of water spiked with < 4 ug/L concentration of 17 anions is directly analyzed.
