The Sauerbrey equation or viscoelastic modeling? – what happens if you use the wrong method?

Quantifying QCM mass, there are two different approaches to choose from, the Sauerbrey equation or viscoelastic modeling. But what if the wrong method is applied, what happens then? How critical are the consequences? Here we describe what happens if the wrong quantification approach is used.
