Determination of Calcium on beer, wort and water
Calcium analysis allows, in a simple and fast way, to quantify the concentration of the analyte in the water used in the brewing process and to control this parameter in the wort during the production process. Calcium reacts with the malt phosphates causing the decrease in pH, promotes enzymatic activity, contributes to the coagulation of proteins, the flocculation of yeast and the precipitation of oxalates.
Method Calcium on Water
Test type: End Point.
Time testing: 2 minutes.
Analysis sessions with multiple samples are possible up to a maximum of 16 tests for CDR BeerLab® and 3 tests for CDR BeerLab® Junior.
Sample treatment
Use sample as it is
Method Calcium on Beer and Wort
Test type: End Point.
Time testing: 8 minutes.
Analysis sessions with multiple samples are possible up to a maximum of 16 tests for CDR BeerLab® and 3 tests for CDR BeerLab® Junior.
Sample treatment
Use on beer and wort. The beer sample needs to be degassed using the ultrasonic bath (code 222062) before taking the sample. For higher accuracy in the analysis of wort we recommend to centrifuge (code 222061) the sample.
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.
