DSC ACTUAL EXAM QUESTIONS WITH
CORRECT ANSWERS 2026
What is DSC ? - CORRECT ANSWER -Differential Scanning Calorimetry
Measures difference in heat flow (absorbed or released) between a sample compared to an
inert, reference as a function of time and temperature
What can DSC tell you ? - CORRECT ANSWER -Identify amorphous and crystalline material
Identify phase transitions and changes of state - Tg, Tm, cold crystallization , polymorphs,
thermal history, degree of cure, freezing point, etc
Specific Heat Capacity
Heat of fusion and reactions
Reaction Kinetics
Oxidative/Thermal Stability, Oxidative induction time
Purity
Enthalpy
, Why is DSC important ? - CORRECT ANSWER -Used to understand critical temperature
transitions of materials to understand how they will perform at specific environmental
conditions, processing conditions, storage, etc.
Plays a large role of material R&D, QC, process development, and manufacturing.
DSC - Formulation/Process Optimization - CORRECT ANSWER -Heat flow events provide insights
into effects of both formulation changes and process changes
Understand how material responds to temperatures throughput manufacturing process and
help develop best fit formulation for balance of production and end performance
DSC - QC - CORRECT ANSWER -Testing raw materials from suppliers to ensure meeting specs
before going into manufacturing
- batch to batch variability
- supplier comparison
Testing end product to ensure meets specifications before going to market
Ensure no product quality decreases
How does DSC function ? - CORRECT ANSWER -A sample pan with sample material and empty
reference pan sit on the sample and reference platforms of the calorimeter
A purge gas is applied - typically N2 or Helium
A temperature profile (-180C to 725C) is applied consisting of cooling, heating, isothermal,
temperature ramping
