Measuring thick coconut oil films and cleanup using QCM-I

This application note describes the data obtained from films of Virgin Cold-Pressed Coconut Oil spin coated onto a MicroVacuum Au coated QCM-I sensor crystal. The QCM-I instrument monitors the impedance spectrum of an oscillating quartz crystal sensor, tracking the changes in the resonant frequency (F0) of its fundamental and overtones as well as their peak widths (Full Width Half Maximum, FWHM), all in Hz.
