Question
Will a colored or cloudy sample interfere with a colorimetric test?
Answer
In a photometric analysis, turbidity and coloration can lead to incorrect results. This can either come from the sample itself or from reactions with the reagents. The influence of turbidity and / or coloration can be determined by determining the sample-specific blank value.  Determining a sample blank requires measuring the sample with no reagents added and then subtracting that value from the test result or using as the blank for the test, depending on method.  See the method you are using for more information.
