Test type: End Point.Time testing: [uni].Analysis sessions with multiple samples are possible up to a maximum of 16 tests for CDR DrinkLab

Method

Place the test tubes containing reagent R1 in one of the incubation cells and let them warm for at least 10 minutes.

Select the cuvette to be read from the display. Place the cuvette in the cell marked with the blue light and press READ.

Collect 20 µL of sample with a pipette. Use a new tip for each test to prevent contamination from previous samples.

Carefully clean the outside of the pipette tip with blotting paper, avoiding contact between the extremity of the tip and the paper.

Place the sample in the cuvette. Keeping the tip immersed in reagent, press and release the piston of the pipette several times.

Place the cuvette in one of the incubation cells and start the timer by pressing  the timer icon.

Insert test tube in the reading cell marked with the blue light.

Sample treatment

The alkaline components of water react with a specific reagent leading to the formation of an adduct which absorbs at the wavelength of 366 nm. The absorbency of the sample is directly proportional to the alkalinity value.

Principle of the test

The calibration curve was constructed using the reference method of potentiometric titration.

Calibration curve

The calibration curve of the alkalinity analysis on water with CDR BeerLab® obtained using the reference method of potentiometric titration. R² = 0.9866
