Working in a surface science lab, you surround yourself with analysis equipment that you need to progress in your work. The benefits of running combination measurements could be three-fold.
QCM-D and ellipsometry are two surface sensitive real-time technologies that can be used in combination to give synergistic effects. To make to most of the combined output data, there are some aspects to consider when setting up the combined experiment and when analyzing the captured data.
The mass extracted by QCM-D and ellipsometry are often not the same. Read about what the difference is between these masses, and why they are not equal.
Thanks to the complementary information combinatorial QCM-D and ellipsometry can provide, these two allow one to simultaneously monitor both polymer brush swelling and deswelling behavior, as well as attachment and detachment of protein.
