• Digestion is required for determining total iron for EPA reporting purposes. See the Hach Water Analysis Handbook for digestion
procedures.
• 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.
• After adding reagent, an orange color will form if iron is present.
• Accuracy is not affected by undissolved powder.
