A Discussion of Different Methods for Specific Heat Capacity (Cp) Determination by Thermal Analysis

Specific heat capacity is a key property for improving technical processes such as injection molding, crystallization as well as for the safety analysis of chemical processes. This webinar covers the definition of specific heat capacity, its importance and methods for measurement.

Date: February 7, 2018
Time: 10 AM EST (7 AM PST)
Duration: 1 hour
Presented by:


The determination of the specific heat capacity at constant pressure (cp) is a common application for solids and liquids. The heat capacity can easily be measured by DSC, or at higher temperatures by TGA-DSC. Sometimes, a so-called non-reversing effect (e.g. evaporation or crystallization) is superimposed on the cp curve. The determination then requires a temperature-modulated technique. In this Webinar, we will discuss the advantages and disadvantages of different cp methods.

Attendees will learn about the following topics:

  • Definition of specific heat capacity, cp
  • Importance of cp
  • Methods
      • Direct method
      • Sapphire method
      • IsoStepĀ® DSC
      • Steady state ADSC
      • ADSC
      • TOPEMĀ®
  • Applications
  • Summary

Key Take-Aways

  • Know the different DSC cp methods
  • Understand what can be achieved regarding cp accuracy by these DSC methods
  • Learn how to measure cp if there are overlapping effects (e.g. evaporation)
  • Learn some tips and hints regarding cp measurements
