Determination of Saccharin concentration in Nickel bath

Analysis of saccharin makes it possible to determine its concentration within the nickel plating bath, contributing to the control of the electroplating process. Monitoring of this additive is essential to ensure that the nickel deposit exhibits the desired characteristics, such as a smooth and bright finish, meeting the required quality standards. In addition, proper management of saccharin allows optimization of additive consumption, improving process efficiency and reducing waste, resulting in both economic and environmental benefits.

Method

Test type: End Point.

Testing time: 6 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 30 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

The sample is dissolved in an appropriate solvent that allows absorbance measurement at a fixed wavelength; the optical intensity is proportional to the saccharin concentration in the nickel bath sample analyzed.

Calibration curve

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