Determination of zinc in water
Zinc analysis with CDR BeerLab® allows, in a simple and fast way, to quantify the concentration of the analyte in the water used in the brewing process.
Method
Test Principle
Zinc reacts in an alkaline environment with a chromogen to form a colored complex, whose absorbance measured at 578 nm is proportional to the amount of analyte present in the water sample.
Calibration curve
The calibration curve was constructed using standard zinc solutions. The trend of the curve confirmed an excellent linearity of the system over the whole measuring range.
