You are welcome and thank you too!!!

Hi huijeanlim, regarding your question, in principle, it is possible to use NEXT electronics with the configuration you showed me (by connecting the right quartz electrode as working). Anyway, actually, in my opinion, it is not possible to use our d…

Hi imjustakay, because you are using a Wi2, you don't need to do anything because this device is based on a Teensy 3.2. As a consequence you can use quartz sensors with higher frequencies, without problems. The 8 MHz limit was valid only for the old…

I am so sorry, Marco (that developed the SW) referred to me that in the exe version this is not possible! Sorry again. My mistake!
-
Hi @Vince90. First sorry for my reply delay. You should find the same files in the exe version.

You are welcome and thank you too!

Hi @huijeanlim.... first sorry for my reply delay. The discussion is more complex than it seems. So, it is better to describe how the temperature affects the frequency baseline behavior. So, in order to exploit the piezoelectric properties of quart…

Hi @huijeanlim, did you intend the "zero" point Temperature?
-
Great @huijeanlim ... your approach is absolutely correct!
-
Hi Vince90, I do not if huijeanlim will answer and how he performed the calibration. Anyway, a temporal lag can be due to the distance from the QCM sensor from the T sensor. As matter of fact each system has its proper thermal inertia. I can only sa…

Your comments are very very interesting!!! Anyway, we are sorry for our reply delay, but in this period we are launching the new openQCM NEXT, so it is a challenging time. Because we believe that your excellent contribution needs a detailed discussi…

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.

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, …

Hi Hui. Thank you very much. I just found your email. We will analyze you data and I will reply as soon as possible. Thank you again!
-
Hi huijeanlim, could you share with us the data file? Please, if possible, write privately to us at info@openqcm.com. Furthermore, did you verify the presence or not of bubbles?
-
Absolutely possible! Marco will explain to you how to do this.

You are welcome!

Are you using wrapped electrodes?

You are welcome and thank you too!

Hi huijeanlim, regarding your question, each quartz has a T-freq dependance. This is due to the variation of the wave propagation along with the quartz thickness. Anyway, it is important to underline that every single quartz has a different T behavi…

Hi SamB, sure, we will share the code here for who will be interested.

Hi Chris2020, sorry for my reply delay. Fist thank you. We are very happy that you are enjoying with openQCM. We have always aimed to obtain open-source instruments that have similar performance to commercial scientific devices. So, your comment is …
-
Are you sure you are connecting the quartz in the right mode?
-
you are welcome!
-
Hi joelvanbeem, absolutely yes. You can use the sensor without a lid. You will observe only a noise increasing due to the sensor exposition to the external environment. On the other hand, you can also use your own sensor head by wiring it to the mai…

Dear huijeanlim, regarding your question... your observation is correct. As a matter of fact, the materials exposed to the solutions are: - Gold electrodes and Quartz - Viton o-ring - PMMA or PTFE - Tygon Tubes It is difficult for me to answer yo…

You are welcome and thank you too. Please let me know if you will solve!

Hi huijeanlim, thank you for your interesting question. regarding your procedure, your impression is right. Sometimes QCM instruments have drifts due to o-ring swelling or other mechanical stress on the sensor. By knocking on the device fluidic cel…
