Extrapolation of several results
Proceed as follows to carry out an extrapolation of several results:
1 Open dialog window
￭ Open the Results window and the database (see "Displaying the
determination overview", page 87).
￭ Select the required determinations (see "Selecting determina-
tions", page 90).
￭ Click on the menu item Determination ▶ Extrapolation.
The dialog window Extrapolation with the extrapolation values
which the program has calculated from the selected results (determi-
nations) appears.
2 Select result and target temperature
￭ Click on the [Settings] button.
The following dialog window appears:
￭ Select the result which is to be used for extrapolation (Induction
time, Stability time, etc.).
￭ Enter the Target temperature.
￭ Confirm the entries with [OK].
Note
The time determined for a particular sample by extrapolation to
low target temperatures (e.g. 25 °C) is a purely theoretical value.
The interrelation between this time and e.g. the perishability of the
sample must be determined experimentally.
