5.11.3 Determination of correction values for NANOCOLOR
®
standard tests with
sample blank value
For the tests of this category, the correction can already be performed during the
measurement. In these cases the following preparations are used as blank values
instead of the blank values given in the instructions.
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 blank value must be
reduced as well.
