Beer

The analysis of bicarbonates allows, in a simple and fast way, to quantify the concentration of the analyte in the water used in the brewing process.CDR BeerLab® allows you to determine the concentration of bicarbonates in the water intended for brewing in a simple and fast way.&nbsp;

Determination of bicarbonate in water used in brewing proces

CDR BeerLab® - simple, fast and reliable analysis system of beer.

Test type: End Point. Time testing: [uni]. Are possible test sessions with several samples, up to 16 for CDR BeerLab® and 3 tests for CDR BeerLab® Junior.<h3>Sample treatment</h3>Use water solution as is.

Method

The bicarbonate ion reacts with an enzymatic complex that leads to the oxidation of NADH. The decrease in absorbance measured at 366 nm is proportional to the amount of the analyte present in the water sample.

R² = 0.9895"></figure>The calibration curve was constructed using standard bicarbonate solutions. The trend of the curve confirmed an excellent linearity of the system over the whole measuring range.&nbsp;&nbsp;
