Determination of Nickel in Gold Flash bath

The determination of nickel concentration in Gold Flash baths is essential to guarantee the purity of the gold deposit and prevent contamination that could alter the shade, adhesion or aesthetic and functional quality of the thin layer. Analytical techniques such as atomic absorption spectroscopy (AAS) or complexometric titration allow accurate monitoring, but the complexity of these methods may require sending samples to external laboratories, extending quality control and decision-making times on the process. With CDR GalvanLab® it is possible to perform a quantitative analysis of nickel with a simple photometric method, optimizing monitoring, reducing delays and improving production efficiency.

Method

Test type: End Point.

Testing time: immediate reading.

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 test tubes containing reagent R1 in one of the incubation cells and let them warm for at least 5 minutes.
Passo 2
Step 2/8
Gently shake the cuvette 2-3 times.
Passo 3
Step 3/8
Place the cuvette in the cell marked with the blue light and press READ to perform the photometric reading.
Passo 4
Step 4/8
Collect 50 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

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

Calibration curve

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