Determination of Iron concentration in Pd-Fe plating bath

Iron analysis allows the quantification of Fe concentration in Pd-Fe electroplating baths. If the amount of Fe in the electroplating bath is less than the expected amount, the electroplating process may be suboptimal, possibly leading to problems with aesthetic defects (e.g. glazing) in the finished products. Therefore, monitoring the concentration of Fe in Pd-Fe baths is critical to ensure the good performance of electroplating processes.

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 1/10
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 2/10
Collect 200 µL of R1a with a pipette.
Passo 3
Step 3/10
Add 200 µL of R1a to the cuvette containing reagent R1 without touching the tip in the liquid. In case of contamination, replace the tip.
Passo 4
Step 4/10
Gently shake the cuvette 2-3 times.
Passo 5
Step 5/10
Select the cuvette to be read from the display. Place the cuvette in the cell marked with the blue light and press READ.
Passo 6
Step 6/10
Collect 50 µL of sample with a pipette. Use a new tip for each test to prevent contamination from previous samples.
Passo 7
Step 7/10
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 8/10
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 9/10
Gently shake the cuvette 2-3 times.
Passo 10
Step 10/10
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 iron content is determined by its reaction with a chromogen that develops a coloration, the optical intensity of which is proportional to the Fe concentration in the analyzed sample.

Calibration curve

The calibration curve was obtained by correlating the CDR method with the reference method.
