In QCM instrument specifications and experimental descriptions, there is always a reference to the fundamental frequency. But does the fundamental frequency really matter? Here we sort out the details and explain how and why it matters in a measurement situation.
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.
One of the key factors to achieve reliable and reproducible QCM measurements is temperature stability. Here we list the top four factors that will help you eliminate temperature induced artifacts in your QCM data.
On the topic of QCM, the different resonance harmonics, i.e., the fundamental and the overtone harmonics, are often subject to discussion. So, what is the deal with the overtones? Are they really needed, and if they are, when and why are they important?
When you are to invest in a new QCM-system, there are several aspects of the instrument to evaluate such as price, experimental capabilities and data quality. Price is straightforward, but how about the other two factors? Here we guide you how to asses experimental capabilities and data quality.
