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 has a temperature sensor with high accuracy based on thermistor and Arduino. The Quartz Crystal Microbalance accuracy depends on temperature.
openQCM the Java application for developers
![openQCM Java software project developed using NetBeans IDE](https://openqcm.com/wp-content/uploads/2015/01/openQCM-Java-software-1.png)
In this post I discuss in detail the development of Java application for the open source quartz crystal microbalance openQCM. This post is intended for developers and contributors of the open source project. The entire project is available on github repository at this link

Hi everybody, This is my first post on the openQCM blog, so I introduce myself. I am Marco, scientific coordinator at Novaetech S.r.l. and now co-founder of the openQCM project the unique open source quartz crystal microbalance. Above all I am a lucky man because I really enjoy my work.
