Colour Standard Reagent 500 Hazen

Cas Number: Mixture Part Number: 2705
Colour Standard (500 Hazen) is a calibration standard. Calibration standard solutions are used for external standard, internal standard, and standard addition approaches to quantitation. The Hazen colour test uses a Pt/Co solution and was developed for water treatment facilities where the colour of water could be used as a measure of concentration of dissolved and particulate material. Slight discolouration is measured in Hazen units (HU). Impurities can be deeply colored as well, for instance dissolved organic compounds called tannins can result in dark brown colors.
