openQCM test of quartz crystal in contact with liquid
![The entire frequency data set of quartz crystal in contact with air and with pure water using two different openQCM instruments](https://openqcm.com/wp-content/uploads/2016/12/openQCM-liquid-entire-test-2-787x1024.png)
Here we report in detail the verification test of openQCM Quartz Crystal Microbalance in contact with pure water according to the theory based on Kanazawa – Gordon equation
Sweet openQCM Tasting Water Sucrose Solutions
![Figure 1 openQCM frequency behaviour caused by successive injections of water and sucrose at different weight percentage 7.5%, 15% and 30%. The measurement chamber is washed with pure water before each injection. The corresponding frequency shift is measured in static liquid at the equilibrium.](https://openqcm.com/wp-content/uploads/2015/06/openQCM-sucrose-test-all-elab-1.png)
I’d like to share openQCM Quartz Crystal Microbalance frequency behaviour in contact with water solutions at different weight percent of sucrose.
openQCM frequency stability of quartz crystal microbalance in typical experimental conditions

We are now testing the performances of two different openQCM devices in the most typical experimental conditions in order to measure the frequency stability of the open source quartz crystal microbalance.
Quartz Crystal Microbalance openQCM: our first test
![](https://openqcm.com/wp-content/uploads/2014/12/Quartz-Crystal-Microbalance-openQCM-Water-Test-1-1024x616.png)
As already mentioned, we have just completed the design and the electronic optimization of the Quartz Crystal Microbalance openQCM. At the moment we already have 2 working devices. So, we are very glad to show the first test in liquid environment. In order to demonstrate the real behavior of the system we have preferred to make a video. In […]
