All dilutions are based on a final volume of 10 mL, so several dilutions will require small
volumes of the water sample. Graduated pipets should be used for all dilutions. If
volumetric glassware is not available, dilutions can be made with the colorimeter tube.
Fill the tube to the 10 mL line with the sample and then transfer it to another container.
Add 10 mL volumes of deionized water to the container and mix. Transfer 10 mL of
the diluted sample to the colorimeter tube and follow the test procedure. Repeat the
dilution and testing procedures until the result falls within the range of the calibration.
Multiply the test result by the dilution factor. For example, if 10 mL of the sample water
is diluted with three 10 mL volumes of deionized water, the dilution factor is four. The
test result of the diluted sample should be multiplied by four.
