Notes

For best results, rinse vials thoroughly between with deionised water.
Ensure that the outside of the vials are clean, dry and free from
fingerprints. Always handle vials by the lid where possible.

The tablets must be added in the correct sequence. Ammonia No. 1
tablet will only dissolve fully after Ammonia No. 2 tablet is added.

The tablets should be added direct from the foil avoiding contact with
hands or surfaces.

The temperature is critical for full sample development. Below 20°C,
increase reaction time to 15 minutes.

The tablets are unsuitable for determination of ammonia in sea water or
brackish water due to precipitation of salts. A solution is available if
necessary.
