[. . . ] High Range - 1000-10000 mg/L Sulfate · Remove the cap from the plastic vessel and fill it with 15 mL of the sample, up to the mark. · Proceed with the test as described before, using HI 38001B-0 HR as titration solution instead of HI 38001B0 LR (fill the other syringe to perform this test). · Read off the milliliters of titration solution from the syringe scale and multiply by 10000 to obtain mg/L (ppm) of Sulfate. SIGNIFICANCE AND USE Sulfate is largely present in natural waters in a wide range of concentrations. It is not toxic but has to be kept below a certain threshold to prevent it from creating an unpleasant taste in water. The concentrations are particularly higher close to mine run-off water. The procedure for determining sulfate is a modification of the Determination of Sulfate by Sulfonazo III. Note: mg/L is equivalent to ppm (parts per million). www. hannainst. com Dear Customer, Thank you for choosing a Hanna Product.
