4.1 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 (measure -
ment 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.
