Preperation
1. Sea water samples:
Ammonia conditioning reagent is required when testing sea water or brackish water
samples to prevent precipitation (settlement) of salts.
Fill the test tube with the sample to the 10 ml mark and add one level spoonful of
Aluminium Conditioning Powder. Close the vials with the caps and swirl until the
powder has dissolved. Then proceed as described.
Notes
1. The AMMONIA No. 1 tablet will only dissolve completely after the AMMONIA No. 2
Tablet has been added.
2. The temperature of the sample is important for full colour development. At tempera-
tures of below 20 °C the reaction period is 15 minutes.
