Factors affecting the

measured value

The following factors can adversely affect the measurement quality:

 The measuring gap is not sufficiently filled and flowed through by the

test sample

 Foreign bodies and air bubbles are in the measuring gap

 Extraordinary changes (interferences) of the sample matrix

 Contaminated measurement windows due to difficult waste water

matrix

 Damaged measuring windows

 Lacking quality of the zero adjustment, e. g. due to contaminated

ultrapure water

 The user calibration is not representative (or erroneous)
