Is the openQCM Q-1 limited to measuring one overtone per measurement? I would like to measure several overtones simultaneously (or at least within a short time interval). Is there a limit in the hardware to achieve this, or could it be possible with software modifications?

Hi Ville,
regarding your question, yes, it is possible monitoring simultaneously overtones. But actually we are working to a new software version in order to enable this possibility. Actually should be possible to scan all frequencies together in about less than 10 sec, but we are also working to a new hardware with a 32 bit ADC in order to drastically increase the scanning time. In any case as soon as we will be ready with multi-overtone measure we will post a news on our official website.

Hi,
That is great! Looking forward to this update, keep up the good work.
Best,
Ville

Hello,
Was this feature already introduced?

Hi Ohad,
Because Marco already replies to you by email, I will report the section related to this discussion:
Actually we're working both on software and electronic development of the openQCM Q-1 device
- software: major change of python software, implements multi-frequency overtone mode of measurement. major change and optimization of the software logic
- electronics: major change of microcontroller and ADC system, in order to improve the ADC data conversion capability of the device, implementing multi-frequency overtone mode of measurement. Plus several electronic add-ons for Temperature active control of the quartz crystal sensor, implementation of electrochemistry measurement.

Hello, wondering if the feature to simultaneously monitor the frequency and dissipation shifts at multiple overtones is currently available on the Q-1 device?

Dear huijeanlim,
Unfortunately, we tried with the Q-1, but it has hardware "too slow" to acquire simultaneous overtones measurement. For this reason, we design a new device "openQCM Next" that will be launch in January.
