  • Determination of Major and Minor Elements in HF-Digested

    MΩ DIW. Calibration standards were prepared from Agilent aqueous single element certified reference materials, at the concentrations shown in Table 3. All calibration standards were matrix matched with the same HNO 3-HF-HCl acid mix in DIW. The calibration range was based on the expected concentration of the analytes in the SRM digests.
