The method describes how to determine the phosphate content of water photometrically with a cuvette test.
Phosphate ions form a yellow color in the presence of the molybdovanadate reagent. The color is determined using a photometer.
Determination of the reductometric properties of a beer.
Suitable for all beers.
Reductones reduce a certain amount of Tillmann's reagent (2,6-dichlorophenolindophenol, DPI) within a certain period of time. The decolourisation of the reagent is measured spectrophotometrically and calculated using the formula given.
Determination of the reductometric properties of a beer.
Suitable for all beers.
Reductones reduce a certain amount of Tillmann reagent (2,6-dichlorophenolindophenol, DPI) within a certain period of time. In the ITT, the time to 80 % decolorization of the indicator solution is determined by visual color comparison.
