Growing interest around the determination of arsenic (As) in fruit juices has been triggered by media reports claiming that some apple juice products may contain high amounts of arsenic. It is more important to detect and quantify inorganic (As(III) and As(V)) than organic arsenic, because inorganic forms of arsenic are highly toxic while the organic forms are not. The established analytical method for the various arsenic species is the separation of them by Ion chromatography (IC) followed by detection using ICP-MS. IC �ICP/MS can be an expensive technique.  Ion chromatography (IC) with suppressed conductivity is a well established, lower cost method used by multiple industries for ion determination.  Recently introduced high-pressure capable capillary IC systems combined with 4-mm particle ion-exchange columns have reduced eluent consumption and further improved separation efficiency. This study presents the detection and quantification of inorganic arsenic (Arsenite As (III)) Arsenate As (V) and Arsenate As (V) Arsenite As (III)) using a high-pressure capillary IC system with 4 �m particle ion-exchange column.
