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

Determination of sulfate in water

Sulfate 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

The sulfate ion reacts with barium chloride to form barium sulfate. The absorbance determined at 420 nm is proportional to the amount of analyte present in the water sample.

Calibration curve

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 sulphates on water with CDR CoffeeLab obtained using standard sulphate solutions. R²=0.9993
