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 83).
￭ Select the required determinations (see "Selecting determina-
tions", page 86).
￭ Click on the menu item Determination ▶ Extrapolation.
The dialog window Extrapolation with the extrapolation values which
the program has calculated from the selected results (determinations)
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 sam-
ple must be determined experimentally.
