Introduction
4. DSC Mechanism
Differential Scanning Calorimetry measures the heat flow difference between a material
sample and a reference under controlled temperature conditions. By applying a specific
heating or cooling regime, DSC can identify and quantify phase transitions in the
sample, such as melting, crystallization, or glass transitions. This is achieved by
observing the endothermic and exothermic events that occur as the temperature
changes, providing a thermal profile or DSC curve of the sample.
6. The accuracy and
reliability of DSC
analysis are
enhanced through
adherence to
established
international
standards:
ISO 11357: Defines the general principles for
DSC analysis, including calibration,
operation, and data interpretation guidelines.
JIS K 7123: Targets DSC testing on plastics,
aligning with global standards to ensure
consistency and reliability in material testing.
ASTM E967: Specifies the procedure for DSC
calibration, ensuring precise temperature and
heat flow measurements.
8. Pharmaceuticals: DSC is crucial for analyzing drug
compounds, assessing their stability, and understanding
polymorphism.
Polymer Science: It provides insights into polymers'
crystallinity, melting points, and thermal transitions,
aiding in material development and quality control.
Food Science: DSC helps in studying lipid oxidation,
protein denaturation, and other critical factors affecting
food stability.
Environmental Studies: The technique is used to examine
the thermal decomposition of materials, contributing to
the development of sustainable materials.
The versatility of DSC makes it a cornerstone
technique in numerous fields:
