Preparation
1. If the water sample is turbid, it must be filtered before performing the zeroing.
2. The sample's temperature should not exceed 21 °C.
Notes
1. When using the hydrazine measuring spoon, 1 g is a level measuring spoon.
2. For removal of the reagents resulting in turbidity, ensure to use a quality membrane
filter for medium deposits.
3. To check the reagent for prolonged storage and possible ageing, follow the test as
described for tap water. Should the result of the value of the detection limit of 0.05
