IC-ICP-MS Speciation Analysis of As in Organic Brown Rice Syrup (OBRS) Using the Thermo Scientific iCAP Q ICP-MS

This application note describes the analysis of organic brown rice samples (OBRS) for their total arsenic content by ICP-MS and their species concentrations by IC-ICP-MS. Determination of the concentration of six arsenic species is described: the two toxic inorganic species (As(III) and As(V)), and four organic species that are considered to be harmless.
