Total Bromine Test
1. Rinse and fill large comparator tube to desired mark with water to be tested.
NOTE: For 1 drop = 0.5 ppm, use 25 mL sample.
For 1 drop = 1.25 ppm, use 10 mL sample.
2. Add 2 dippers R-0870. Swirl until dissolved. If total bromine is present, sample will turn pink.
NOTE: If pink color disappears, add R-0870 until color turns pink.
3. Add R-0872 dropwise, swirling and counting after each drop, until color changes from pink to
colorless.
4. Multiply drops in Step 3 by drop equivalence (Step 1). Record as parts per million (ppm) total bromine.
