Determination of zinc in water used for making coffee.
Zinc analysis with CDR CoffeeLab allows, in a simple and fast way, to quantify the concentration of the analyte in the water used in the brewing process.
Zinc reacts in an alkaline environment with a chromogen to form a colored complex, whose absorbance measured at 580 nm is proportional to the amount of analyte present in the water sample.
The calibration curve was constructed using standard chloride solutions. The trend of the curve confirmed an excellent linearity of the system over the whole measuring range.
