Introduction to matrix correction

There are various options available for sc probes to correct the probe value by means of laboratory
values (as a reference value).
This example uses the AN-ISE sc probe, for which the sample laboratory value can be entered as
either nitrate nitrogen (NO
value measured by the probe. For precise information, please refer to the calibration/matrix
correction chapter of the AN-ISE sc user manual.
LINK2SC supports matrix correction 1 and 2 and makes an independent decision as to which of the
two correction types is to be used for the application. The comparison measurements should be
taken on different days and at different times in order to record a maximum number of changes in
concentration. The following table describes the two correction types in more detail.
