• Digestion required. See 2.3 Digestion in the Laboratory Practices section of the DR/2400 Procedures Manual.
• If only dissolved manganese is to be determined, filter the sample before acid addition.
• For more accurate results, determine a reagent blank value for each new lot of reagent. Follow the procedure using deionized
water in place of the sample. Subtract the reagent blank value from the final results or perform a reagent blank adjust. See the
instrument manual for more information on Running a Reagent Blank.
