3.4. Stability
An isochronous short-term stability study was conducted to
establish suitable transport conditions. The same method as
described for homogeneity measurements was used. For both test-
ing temperatures, i.e. 18 C and 60 C, and for both materials, no
outliers were detected. Regression analysis revealed no significant
trends for both temperatures and both materials (Fig. 2). Table 4
lists the figures calculated from the regression analysis. It can be
concluded that materials can be dispatched at room temperature
without compromising the material’s stability. It shall be noted
