There is a vast range of different QCM:s in the market, and they all seem to provide similar information. Learn more about the differences, and when to use which one.
The quartz crystal microbalance, QCM, has been around since the 60’ where it has been used for monitoring of thin-film deposition and characterization of thin films. So how does this technology work?
Model membranes are used in various fields of research. Read about how these lipid membranes can be characterized using QSense QCM-D technology.
Proteins tend to passively adsorb to surfaces. Read about how protein adsorption at various surface and solution conditions quickly can be measured.
What is piezoelectricity and how does it work? Here we explain the piezoelectric effect and how this remarkable property arises.
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?
