Multiple Sample Differential Scanning Calorimetry

  • Robert C. Johnson
  • Valdis Ivansons


We shall describe the design and performance of multiple sample instruments for differential thermal analysis which do runs on several samples simultaneously1,2,3.The first of these is a five sample DTA system that served as a basis for the DSC system. Following this is a description of the principles of operation of the isothermal boundaries that were formed as integral parts of the heating block and thermoelectric disk of a heat flow type multiple sample DSC cell.
