SP600 Spectrophotometer 01/2008

1.1 Methods

Notes:

1. Use deionized water or tap water free of Cyanuric acid.
2. If Cyanuric acid is present a cloudy solution will be given.
Single particles are uncaused necessarily by Cyanuric acid.
3. Dissolve the tablet completely (therefore swirl the vial approx. 1 minute).
Not dissolved particles of the tablet can cause too high results.
