Color Master
PHOTOMETRIC COLOUR ANALYSER
Color Master is Chemitec’s sophisticated system for automated photometric colour analysis in water-treatment applications. The all-in-one system delivers precise, repeatable process measurement results while its low maintenance requirement makes it a cost-effective choice.
APPLICATIONS
- Industrial effluent
- Potable water
- Pulp and paper
- Wastewater
- Food and beverage
COLOUR ANALYSIS
The analytical procedure is used for spring waters, groundwater, water from rivers and lakes and water destined for human consumption after appropriate treatment. The method can be applied to samples with the base colour similar to that of the platinum cobalt reference solution (yellow-brown).
The colour of water is generally caused by organic substances such as humic and fulvic acids (to which a yellow-brown colouring may be assigned) or by salts of some metals such as iron, copper and manganese.
Observing the light transmitted through a thickness of a few metres, the colour of water is variable in blue shades, while the presence of coloured foreign substances causes a variation of colour in infinite shades. The apparent colour, caused by substances dissolved and suspended into the water, must therefore be distinguished from the actual colour.
