AN43126: IC-ICP-MS speciation analysis of As in Organic Brown Rice Syrup (OBRS)
Description
Inorganic and organic arsenic compounds have very different toxicities, and therefore speciation analysis is needed to assess the potential health risk posed by the food product. Here two inorganic and four organic arsenic species are determined in an Organic Brown Rice Syrup (OBRS) sample using IC coupled to ICP-MS. Arsenic species are first separated by IC using an ammonium carbonate gradient on a IonPac AS7 column. Then the eluting species are detected and quantified by the ICP-MS down to ng/g concentrations. Arsenic speciation is also demonstrated in apple juice samples (AN43099).| Market: | Food and Beverage |
