tn62 reducing carbonate interference anion determinations with carbonate removal device crd trace anions


Carbonate 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.
