Abstract
Method for detecting a change in mass with a quartz crystal impedance-scanning microbalance, which can be connected to an evaluation device, wherein the quartz crystal microbalance is designed to transmit the measurement points recorded at a predetermined data recording rate as raw data to the evaluation device, including at least the following steps: linearly fitting the measurement points of the raw data to a fractional rational function and determining at least one resonance frequency from the fitted measurement points of the raw data, wherein a change in the at least one resonance frequency corresponds to an effective change in mass.
