When applying a quartz crystal microbalance (QCM) to ultra-micromass measurement, not only the electroded region but also the nonelectroded region absorb analytes. The mass loading on the sensing surface of the QCM chip (with both electroded and nonelectroded regions) causes a shift in the frequency of the QCM. A method based on the integral of the mass sensitivity function is presented in this paper which can distinguish between the frequency shift caused by the electroded region and that caused by the nonelectroded region. Finally, the feasibility of the correction method can be confirmed on the basis of the data processing results of an airborne Vaccinia virus testing experiment using a QCM.
