Measuring Thick Coconut Oil Films and Cleaning using QCM-I

Posted by gamry on March 11, 2021

Measuring Thick Coconut Oil Films and Cleaning using QCM-I QUARTZ CRYSTAL MICROBALANCE with IMPEDANCE (QCM-I) detection Micron-thick films of Coconut Oil can be formed by spin-coating and the thickness of the solid films estimated using QCM-I. The viscoelastic changes in the layers can be observed during melting and subsequent structural reorganization on re-solidification.

Principles of QCM-I

Posted by gamry on April 18, 2019

The Quartz Crystal Microbalance is a well-established and sensitive technique used to measure the interactions of molecules, polymers and biological assemblies with a sensor surface, in air or liquid, label-free and in real time. It is based on the change in resonant frequency of a quartz crystal sensor when it is covered with a thin film or liquid.
