Figure 2
Calorimetric scan of the melting of a pure Sn reference sample with and without the X-ray beam, which was set to 11.1 keV, where the absorption by Sn is high. The small shift in the baseline might originate from the X-ray absorption or from a repositioning of the sample. The resulting temperatures and enthalpies are reliable in both cases, since they are unaffected by the X-rays and are in good agreement with literature values. |
