5.11.2 Determination of correction values for NANOCOLOR
®
standard tests with
reagent blank value
For tests of this category, the instructions require distilled water plus reagents as a
reagent blank value. Another volumetric flask 25 mL is necessary for the correction
value. Distilled water is used as a blank value for the correction value.
For some tests, a special reagent has to be prepared for correction. If reduced
sample volumes are used for a test (dilution due to concentrations which are too
high), the sample volume for determination of the correction value must be reduced
by the same amount.
