Determination of Sulfate concentration in process water

Sulfate analysis allows for quick and easy monitoring of the analyte concentration present in wash water. Sulfate monitoring is critical to preserving process quality and optimizing operational efficiency.

Method

Test type: End Point.

Testing time: 1 minute.

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
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 500 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

Sulfate ions react with the chromogen in the reagent and generate colored complexes whose absorbance 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.
