Procedure
1. Place the demonstration stage (1038) on an overhead projector and turn
on the projector light.
2. Fill test tube (0820) to the 5 mL line with sample water and transfer this
liquid to a cell on the demonstration stage (1038).
3. Because the invert/shaking of this test is critical, the sample must be
reacted in the tube. Follow instructions from the Field Test Method and
pour over into second cell on demonstration stage.
4. A faint pink color will indicate that a trace of Nitrate is present. High
concentrations of Nitrates will produce a deep magenta color.
