A new simultaneous DSC/X-ray measurement system was developed for the
purpose of combining X-ray scattering data and calorimetric data. The
DSC/X-ray measurement system was equipped with a conventional wide-ang
le X-ray diffractometer (WAXD). The phase transition behavior of pure
hexatriacontane was measured by the DSC/WAXD, both on heating and cool
ing. The accuracy and reproducibility of the simultaneous DSC/X-ray in
strument were comparable with the conventional DSC.
