Quartz crystal microbalance technology, QCM, has been around since
the 60’. Since then, the traditional QCM configuration has been further developed and extended versions, such as QCM-D, now exist.
In this overview, we present the fundamentals of how
QCM and QCM-D technology work.
The overview includes: 
- The measurement principles
- Difference between QCM and QCM-D
- Description of the difference between single-harmonic and multi-harmonic QCM-D
