SAMPLE DILUTION TECHNIQUES

If a test result is out of the range of the meter, it must be diluted. The test 

should then be repeated on the diluted sample. The following table gives quick 

reference guidelines for dilutions of various proportions.

Amount of Sample

Deionized Water to Bring 

Final Volume to 10 mL

Multiplication Factor

10 mL

0 mL

1

5 mL

5 mL

2

2.5 mL

7.5 mL

4

1 mL

9 mL

10

0.5 mL

9.5 mL

20

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.
