Measuring principle
Photometric Measurement The sample is mixed with one or more reagents to adjust the pH, mask possible interferences and form a colored complex with the substance being measured. When the reaction is complete the light absorbance of the complex is measured at a specific wavelength and this value is used to calculate the concentration.
Reagent Calibrant Sample
