Abstract
The quartz crystal microbalance provides critical measurement capability for a wide variety of in situ and in vivo applications. However, it suffers from an underdeveloped connection to the SI (International System of Units). Here, a vacuum metal deposition system is used to deposit films of various masses on to the quartz crystals. The frequency change, which is proportional to the mass shift through the Sauerbrey equation, is compared to gravimetric based mass measurements using SI traceable mass artifacts.
Highlights
The commercial availability and low cost of the quartz crystal microbalance or QCM makes it highly attractive for a wide range of uses
The frequency change, which is proportional to the mass shift through the Sauerbrey equation, is compared to gravimetric based mass measurements using SI traceable mass artifacts
The realization will be performed in vacuum and reliable methods to move from vacuum to air are required [5] because the sorption process that occurs when moving between environments can shift the mass of the artifact from its calibrated value to a new, unknown value
