Determination of Calcium concentration in process water

Calcium analysis makes it possible to quantify the concentration of Ca2+ in galvanic process wash waters. Monitoring the amount of calcium in water is important to ensure the high quality standards of the electroplating industry required by the market.

Method

Test type: End Point.

Testing time: 2 minutes.

Analysis sessions with multiple samples are possible up to a maximum of 16 tests for CDR GalvanLab® and 3 tests for CDR GalvanLab® Junior.

Passo 1
Step 1/11
Place the test tubes containing reagent R1 in one of the incubation cells and let them warm for at least 5 minutes.
Passo 2
Step 2/11
Collect 200 µL of R2 with the pipette.
Passo 3
Step 3/11
Add 200 µL of R2 to the cuvette without touching the tip in the liquid. In case of contamination, replace the tip.
Passo 4
Step 4/11
Place the cuvette in one of the incubation cells and start the timer by pressing the timer icon.
Passo 5
Step 5/11
Place the cuvette in the cell marked with the blue light and press READ to perform the photometric reading.
Passo 6
Step 6/11
Collect 25 µL of sample with a pipette. Use a new tip for each test to prevent contamination from previous samples.
Passo 7
Step 7/11
Carefully clean the outside of the pipette tip with blotting paper, avoiding contact between the extremity of the tip and the paper.
Passo 8
Step 8/11
Place the sample in the cuvette. Keeping the tip immersed in reagent, press and release the piston of the pipette several times.
Passo 9
Step 9/11
Gently shake the cuvette 2-3 times.
Passo 10
Step 10/11
Place the cuvette in one of the incubation cells and start the timer by pressing the timer icon.
Passo 11
Step 11/11
Place the cuvette in the cell marked with the blue light and press READ to perform the photometric reading.

Sample treatment

The sample can be used as is.

Principle of the test

Calcium ions react with the chromogen in the reagent and generate colored complexes, whose absorbance measured at 580 nm is proportional to the concentration of the analyte in the sample.

Calibration curve

Calibration curve was obtained by correlating the CDR method with the reference method.
