Question
Can a turbidity sample be diluted if it is outside the upper range of my turbidimeter?
Summary
Diluting sample for turbidity measurement
Answer
It is best to use an instrument that can measure your sample without dilution, because dilution can alter the characteristics of the suspended particles and produce erroneous results. When necessary, you can dilute samples using a portion of filtered sample. Deionized or distilled water should not be used for dilution water, because some of the turbidity in the sample may dissolve. Use the Sample Filtration and Degassing Kit (Product # 4397510) for filtering the sample. After dilution and measurement, multiply the displayed result by the dilution factor.
