Interpretation of the measurements
Based on the observations of the pre-test (darker colour, sunken baseline) the endotherm event should be indicated as boiling point under decomposition. The event was evaluated with onset function; the beginning and ending were evaluated with event marker function.
Results
For the calculation of the values of the mean and the standard deviation, only the second and third determination was taken into account.
