Required for free copper measurement in water samples.
Copper (Free) Color Disc Test Kit is required for free copper evaluation in the range of 0 - 4 mg/L Cu in water samples. Color Disc/Bicinchoninate method is used to conduct free copper analysis. Model CU-5 can be used for 100 samples. The smallest increment is 0.1 mg/L Cu.
CU-5 Test Set contains:
- CuVer® 1 Copper Reagent Powder Pillows (p/n 1421199)
- Copper Color Disc, 0-4 mg/L (p/n 9263300)
- Color Comparator Box (p/n 173200)
- 18 mm Glass Viewing Tubes (p/n 173006)
- Stoppers for 18-mm Glass Tubes and AccuVac Ampuls (p/n 173106)
Procedure for Cu determination
Before starting analysis:
- Use sunlight or lamp as the source of light to match the color with the color comparator box.
- Rinse tubes with sample before the analysis.
- Rinse tubes with deionized water after the analysis.
Testing procedure
Add 5 mL of sample into two tubes. Place the first tube into the left opening of the color comparator box. Pour the content of CuVer 1 Copper Reagent Powder Pillow into the second tube, set the stopper and invert to mix. The purple color develops as the result of the reaction. After 2 minutes, insert the second tube into the color comparator box. Rotate the color disc to identify the matching color. Read the testing results in mg/L in the scale window.
