Determination of Total Organic Carbon in process water

TOC analysis allows the quantification of Total Organic Carbon in galvanic process waters. Monitoring this parameter 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: 10 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 1/8
Place the cuvette containing the reagent R1 in one of the incubation cells and start the timer by pressing the timer icon.
Passo 2
Step 2/8
Gently shake the cuvette 2-3 times.
Passo 3
Step 3/8
Select the cuvette to be read from the display. Place the cuvette in the cell marked with the blue light and press READ.
Passo 4
Step 4/8
Collect 1000 µL of sample with a pipette. Use a new tip for each test to prevent contamination from previous samples.
Passo 5
Step 5/8
Carefully clean the outside of the pipette tip with blotting paper, avoiding contact between the extremity of the tip and the paper.
Passo 6
Step 6/8
Place the sample in the cuvette. Keeping the tip immersed in reagent, press and release the piston of the pipette several times.
Passo 7
Step 7/8
Gently shake the cuvette 2-3 times.
Passo 8
Step 8/8
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

Total Organic Carbon content is determined by its reaction with a chromogen that develops a coloration, the optical intensity of which is proportional to the concentration of Organic C in the analyzed sample.

Calibration curve

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