Thermoanalytical scanned data
Examination of the kinetic characteristics for a given reaction
are performed on the basis of data obtained under certain
thermoanalytical conditions (e.g. arbitrarily chosen sample
mass, gas flow, and gas composition). These variables emanate
from the different ranges/capacities of distinctive
thermoanalyzer equipment. Generally, these variables are in the
following ranges: sample weight 1-1000 mg, gas flow 10-500
mL/min, and concentration of the reactive or evolved gas 0-100
vol%. The n-dimensional space containing all n-possible
thermoanalytical conditions applied in conventional
thermoanalyzers is thus well-defined. However, kinetic
characteristics are calculated only for one point of this space,
determined by the set of thermoanalytical conditions used.

| If for
the sake of simplicity, we consider only three thermoanalytical
variables: the sample mass S, the flow rate of the carrier gas F,
and the concentration of the reactive gas C, then a 3-dimensional
space (S,F,C) containing the possible thermoanalytical conditions
can be represented as shown in the Figure. |
