Reprocessing a
curve (rules) The so-called “Reprocess“ method must satisfy a few conditions
regarding the original method the curve comes from.
1. Same electrode and reagent systems,
2. Same sample preparation (diluted or non-diluted samples),
3. Same type of result unit (volume or mass units),
4. Same type of titration (Direct titration or Back titration),
5. Conditions on the titration mode :
EP or IP mode for a curve obtained in IP,
EP only for a curve obtained in EP.
6. For a reagent calibration method: same reagent ID.
In Automatic mode, it is recommended to create the so-called
“Reprocess“ method by copying the titration method the curve
comes from. Then you have just to change the desired
parameters.
When editing the so-called “Reprocess“ method, you can change the
following parameters (the other parameters are useless if changed or
can lead to errors while running the curve reprocessing):
End point method:
Edit method menu: Mode (with condition no.5, see above),
Parameters menu: Direction, Number of EP, Value of EP,
Sample menu: no change possible,
Results and Printouts menus: All parameters can be changed (with
condition no.3, see above),
QC Data menu: Minimum value and Maximum value for each result.
Continuous IP, monotonic IP and dynamic IP methods:
Edit method menu: Mode (with condition no.5, see above),
Parameters menu: Direction, IP Filter, IP Reject, Number of IP,
Minimum and Maximum ordinates for each IP,
Sample menu: no change possible,
Results and Printouts menus: All parameters can be changed (with
condition no.3, see above),
QC Data menu: Minimum value and Maximum value for each result.
