CDR CoffeLab analyzer for controlling fermentation processes, for defining the chemical profile of green beans, roasted coffee and the drink.

Determination of Calcium on water

Calcium analysis allows, in a simple and fast way, to quantify the concentration of the analyte in the water used for making coffee.


Test Principle

Calcium reacts with a chromogen and generates a colored complex, whose absorbance measured at 580 nm is proportional to the amount of the analyte present in the sample.

Calibration Curve

The calibration curve was made using calcium solutions with known value. The trend of the curve confirmed an excellent linearity of the system over the whole measuring range.
