What are the Techniques Used in Gravimetric Analysis?
Several techniques are employed in gravimetric analysis within nanotechnology, including:
1. Thermogravimetric Analysis (TGA): TGA measures the change in mass of a nanomaterial as it is heated, providing insights into thermal stability, composition, and possible decomposition products.
2. Microgravimetry: This technique involves highly sensitive balances to detect minute mass changes in nanomaterials, often in the range of micrograms or less.
3. Quartz Crystal Microbalance (QCM): QCM is used to measure mass changes on the surface of a quartz crystal resonator. It is particularly effective for studying thin films and surface-bound nanoparticles.
