What is Isothermal Microcalorimetry (IMC)?

Isothermal Microcalorimetry (IMC) is a highly sensitive analytical technique that measures the heat flow in chemical and physical processes under constant temperature. IMC enables the precise detection of thermal reactions, including phase transitions, binding events, and metabolic processes, making it invaluable in fields such as pharmaceuticals, materials science, and battery research. By monitoring minute changes in heat flow, IMC offers insights into reaction kinetics, stability, and thermodynamic profiles, enabling scientists to characterize complex processes that are often undetectable by other methods.

IMC operates by isolating the sample in a controlled environment and maintaining a stable temperature, allowing any changes in heat flow to be attributed solely to the sample’s internal reactions. Using highly sensitive sensors, IMC detects even the slightest variations in heat—whether exothermic (heat-releasing) or endothermic (heat-absorbing). By capturing these changes in real time, researchers can monitor ongoing reactions over extended periods, yielding detailed profiles of energy exchange throughout the process.

IMC’s versatility extends across various applications, including:

• Pharmaceuticals: Monitoring drug stability, protein-ligand binding, and formulation interactions.
• Biologics: Studying cellular metabolism, microbial growth, and enzyme activity.
• Material Science: Assessing the durability, reactivity, and phase changes in materials.
• Battery Research: Understanding battery performance, degradation, and thermal behavior during cycling.

In battery testing, understanding heat generation and temperature stability is crucial for assessing performance, safety, and longevity. Batteries undergo various chemical and electrochemical reactions during charge-discharge cycles, producing heat as a byproduct. IMC enables precise monitoring of these thermal events, providing insights into battery efficiency, potential degradation, and risks of overheating or failure. This data is essential for optimizing battery performance and safety, especially in high-energy applications such as electric vehicles and grid storage.
