Determination of measured values

Fig. 4-1 Determination of measured values

During a measurement, the absorbance spectrum of the test sample is

recorded and set against the stored absorbance spectrum of a zero

adjustment (measurement in ultrapure water). The algorithm for the

calculation depends on the selected application and/or the measuring

location. The resulting raw value can be adjusted to an independent

reference measurement with the aid of a so-called user calibration.
