QCM-D is designed to detect minute variations in frequency, f, and dissipation, D. Here we have compiled a checklist that will help you optimize the reproducibility of your QCM-D measurements by minimizing unintentional changes of the recorded parameters.
Most commonly used methods to study reservoir wettability are Amott-Harvey, USBM, and sessile drop contact angle.
Studying protein interaction with various surface materials and at different solution conditions, the conditions that minimize adsorption can be identified. Here we show you one way to do this assessment.
Dynamic contact angle measurements with the needle method has been automated for reliable and repeatable results.
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.
