*WARNING: Reagents marked with an * are considered to be potential health hazards. To view or print a Material Safety Data Sheet (MSDS) for these reagents go to

To order individual reagents or test kit components, use the specifi ed code number.
Read the LaMotte Direct Reading Titrator Manual before proceeding. The Titrator is
calibrated in parts per million (ppm) QAC; each minor division equals 20 ppm.
NOTE: High water hardness levels above 600 ppm may interfere. A dilute HCl solu-
tion may be added to lower the pH to 2-5 to compensate for the interference.
PROCEDURE
1. Use the syringe, or other available device, to add 5 mL of sample water to the test
tube (0715). Dilute to 15 mL line with QAC-free tapwater or distilled water.
NOTE: Other sample sizes may be used to extend the range of the test. Use the
table below to determine sample size and appropriate multiplication factor for the
Titrator reading from Step 5.
Range Sample Size Multiply Titrator reading by:
0-5000 ppm 1.0 mL 5
0-2500 ppm 2.0 mL 2.5
0-2000 ppm 2.5 mL 2
2. Add 5 drops of *QAC Indicator Solution (6413). Cap and mix. Solution will turn
green. Solution will turn brown if no QAC is present.
3. Fill Direct Reading Titrator (0384) with QAC Titration Solution (6412).
4. While gently swirling the tube, slowly press the plunger to titrate until the green
tint just disappears and the solution turns brown.
5. Read the test result directly from the scale where the large ring on the Titrator
meets the Titrator barrel. If using a sample size other than 5 mL, multiply Titrator
result by the appropriate multiplication factor. Record as ppm QAC.
6. Thoroughly wash the test tube with the brush (0514). Rinse with clean water after
each test.
