Dynamic Mechanical Analysis Method

Dynamic Mechanical Analysis (DMA) is an official method employed to ascertain moisture content within a material. This technique involves applying an oscillating force to the sample while gauging its response. The sample's stiffness and damping properties are then analyzed to deduce its moisture content.

How DMA Works

Key aspects of DMA include:

Oscillating Force Application: An oscillating force is exerted on the sample, causing it to deform.
Response Measurement: The sample's response, including its deformation and energy dissipation, is recorded.
Moisture Content Determination: The sample's stiffness and damping properties are analyzed to infer its moisture content.

Benefits of DMA

Precise and Reliable: DMA yields precise and reliable moisture content measurements.
Non-Destructive: The method does not damage the sample, enabling subsequent analysis.
Versatile: DMA can assess moisture content in a wide array of materials.

Applications of DMA

DMA finds applications in diverse industries, including:

Pharmaceuticals: Verifying moisture content in pharmaceutical products.
Food Processing: Determining moisture content in food products.
Materials Science: Investigating moisture-induced changes in material properties.
