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.
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
All materials are specifically selected in order to have the best thermal performances and the widest range of chemical compatibility with your samples.
Multi frequency compatibility
Our fluidic module is able to host quartz at different frequencies. A unique quartz crystal fluidic chamber compatible with a wide range of sensors
We have kept in mind thermal performances by designing each mechanical component of openQCM NEXT from scratch
OpenQCM NEXT design is the synthesis of all feedback received from the scientific community. We have come up with a characteristic bridge design, realised with the aim of maximising the thermal dissipation and electrical interferences of the electronics.
