Notes:
1. For correct dosage the spoon supplied with the reagents must be used.
2. This test is suitable for determining free soluble Zinc. Zinc bound with strong complexing
agents will not be measured.
3. Cationics such as quaternary ammonium compounds will cause the colour to change
from rose red to purple, depending upon the level of copper present. In this event add
drops of KS89 (cationic suppressor) one at a time, mixing between additions until the
orange/blue colour is obtained.
