Description This work presents data from Knudsen cell mass spectrometry coupled with differential scanning calorimetry. Instrument STA 409 CD/QMS 403/5 SKIMMER from firma Netzsch applied for investigation of nickel based alloys as well as newly developed steels illustrates modern way how to collect source data leading to estimation of activities for particular components very trigly and effectively. Some data are compared with older ones obtained using home made equipment coupled with a monopole mass spectrometer. Final data can be subsequently used for determination of thermodynamic properties using thermodynamic models involved in CALPHAD method.
