APPLICATION: Swimming pool water.
RANGE: 5–150 ppm Cyanuric Acid
MDL: 10 ppm
METHOD: A buffered solution of melamine forms a precipitate with
cyanuric acid in proportion to the amount of cyanuric
acid present. The amount of particles in suspension is
measured turbidimetrically.
SAMPLE HANDLING &
PRESERVATION:
Cyanuric acid samples should be analyzed as soon as
possible after collection. Deterioration of the sample
can be minimized by keeping samples in the dark or
refrigerated until analysis can be performed.
INTERFERENCES: No known interference from compounds normally found
in pool water. Temperature of the sample should be
maintained between 70°F and 80°F for best results.
Check for stray light interference (see p. 17).
