摘要
The present invention provides a method for a method for measuring the properties of liquid based on a quartz crystal microbalance sensor, which employs two measurements to obtain two frequency shifts of the QCM sensor induced by two different volume of the sample liquid. The present invention creatively established the relationship between the density and viscosity of sample liquid and the frequency shifts of QCM sensor. With present invention, the density and viscosity of sample liquid can be obtained through two frequency shifts. Comparing to the conventional liquid property measurement. The measuring procedure of present invention are more simple, and the measuring results are more accurate. Moreover, the present invention consumes less volume of sample liquid, and has the features such as online, real time and quantitative.
