Both techniques are suitable for meeting the United States Pharmacopeial Convention (USP) Chapter <232> concentration limits, but the sample preparation procedure may dilute the analytes of interest to concentrations below the detection limits of an ICP-OES. ICP-MS provides a larger dynamic range, ...
