PROCEDURE B:<br />
BROMINE IN THE PRESENCE OF CHLORINE<br />
1. Press and hold ON button until colorimeter turns on.<br />
2. Press ENTER to start.<br />
3. Press ENTER to select <strong>TEST</strong>ING MENU.<br />
4. Select ALL <strong>TEST</strong>S (or another sequence containing 9 Bromine-LR)<br />
from <strong>TEST</strong>ING MENU.<br />
5. Scroll to and select 9 Bromine-LR from menu.<br />
6. Rinse a clean tube (0290) with sample water. Fill to the 10 mL line with<br />
sample.<br />
7. Insert tube into chamber close lid and select SCAN BLANK.<br />
8. Rinse a second clean tube (0290) with sample water. Fill to the 10 mL line<br />
with sample. Add 5 drops of Glycine Solution (6811). Cap and mix.<br />
9. Remove blank from colorimeter. Pour out all of the sample water. To this<br />
tube add just enough of Glycine treated sample (Step 8) to cover a tablet.<br />
Add one *Chlorine DPD#1 Instrument Grade Tablet (6903). Crush tablet<br />
with a tablet crusher (0175). Add all remaining Glycine-treated sample.<br />
Cap tube and shake until tablet dissolves. Solution will turn pink if<br />
bromine is present. Wait 15 seconds. Mix.<br />
10. Insert tube into chamber, close lid and select SCAN SAMPLE.<br />
11. Press OFF button to exit to previous menu or make another menu<br />
selection.<br />
PROCEDURE C: FREE AVAILABLE, TOTAL AVAILABLE &<br />
COMBINED CHLORINE IN THE PRESENCE OF BROMINE<br />
1. Perform the test for free and combined chlorine as previously described.<br />
2. Perform the test for bromine in the presence of chlorine.<br />
3. Calculations:<br />
Residual Bromine (ppm) = Reading BR<br />
Free Chlorine in the Presence of Bromine =<br />
Free Chlorine 0.45 (Reading BR)<br />
Total Chlorine in the Presence of Bromine =<br />
Total Chlorine 0.45 (Reading BR)<br />
Combined Chlorine in the Presence of Bromine =<br />
Total Chlorine Free Chlorine<br />
NOTE: Combined chlorine is not affected by the presence of bromine, so the<br />
calculationisthesameaswhenonlychlorineispresent.<br />
