Concentration prediction:Before testing the water sample, the color value of the water sample should be predicted first, and the concentration should be diluted after measurement, for example, the predicted color concentration value is 0-500PCU.You can directly follow the operation steps; If the predicted color value exceeds 500 PCU, the water sample should be diluted to the range of 0-500 PCU for determination.
Notes:It should be determined by a φ25mm cuvette or cuvette (Class B instrument). Avoid using φ16mm cuvettes.
1 1. When the predicted value is 0-500 PCU range
Analytical Procedure: Chromaticity; Watch out for overrange tips!
2. When the predicted value exceeds 500 PCU
The water sample needs to be diluted to the 0-500 PCU range above, and then manipulated according to the corresponding range, and the determination result is multiplied by the dilution factor.
