openQCM NEXT
Finally an open SOurce QCM with Thermal Control and simultaneous multiple overtone measurement
openQCM NEXT is the further step starting from openQCM Q-1 concept, by integrating an active thermal control and the possibility to acquire simultaneous multi-overtone. Furthermore, we have completely re-engineered this instrument by using new materials that take into account the chemical compatibility for most of the samples that you will be used.
Frequency, dissipation and phase measurements
openQCM Q-1 is based on AD8302 RF/IF Gain and Phase Detector which is a fully integrated system for measuring gain/loss trought quartz sensor and phase difference between actuation and sensor reaponse.
Simultaneous Overtones
Thanks to DDS technology and improved speed capabilities of Teensy 4.0, openQCM NEXT is capable to simultaneously interrogate quartz sensor, from fundamental frequency up to the 9th overtone (@ 5 Mhz), in less than 1 sec.
DDS sweep technology
openQCM Q-1 measures frequency and Q-factor by sweeping around sensor resonance frequency thanks to the use of AD9851 component. AD9851 is a CMOS high speed DDS/DAC Synthesizer, which is capable of generate an sine wave with an arbitrary frequency from 0 to 60 MHz.
Built-in Thermal Control
Thanks to an integrated Peltier module, openQCM NEXT has a bi-directional thermal control from 15 °C to 45 °C
all metal fluidic chamber
A flexible holder design to host quartz with different frequencies. A unique quartz crystal chamber compatible with a wide range of sensors
Multi frequency compatibility
Our holder is able to host quartz at different frequencies. A unique quartz crystal fluidic chamber compatible with a wide range of sensors
We designed keeping in mind the concept of modularity
The modular design give us the maximum flexibility for future improvements. For example, it would be easier to modify the original main electronic design, based on the feedback coming from the scientific community, without the need to change the whole device.
