In 1959 Sauerbrey developed an empirical equation to describe the mass sensitivity of gas phase mass deposition on a piezoelectric quartz crystal——Sauerbrey equation:ΔF=〓=-CΔm, where ΔF is measured frequency shift, in Hz; F〓 is the fundamental resonant frequency, in Hz;Δm is mass change, in g; A is piezoelectrically active area , in cm〓;μ〓 is shear modulus of quartz, 2. 947×10〓g· cm〓;ρ〓 is density of quartz, 2. 648g·cm〓; C is mass sensitivity constant , in 〓.

1959年，Sauerbrey最先提出了将压电晶体谐振器用作定量测量质量的装置，并从理论上导出了频率与质量变化之间的关系式——Sauerbrey方程：ΔF=〓=-。。。
