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.
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.
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.
Thanks to an integrated Peltier module, openQCM NEXT has a bi-directional thermal control from 15 °C to 45 °C

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.
