Traceability of frequency based mass measurements using a quartz crystal microbalance

摘要

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.
