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

Analisi del magnesio in acqua

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


Test Principle

Magnesium reacts with a chromogen to form a colored complex, whose absorbance measured at 620 nm is proportional to the amount of analyte present in the water sample.

Curva di taratura

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.

The calibration curve of the analysis of magnesium on water with CDR CoffeeLab obtained using standard magnesium solutions. R²=0.9998
