In short:
1 We measure the frequencies of the overtones of an empty gold sensor (from n1 to n13).
2 Then, we add some chemical of compound eg. oil by spin coating.
3 After this, we measure the overtones on the coated gold sensor (from n1 to n13).
Questions:
How can we measure deposited mass change (f value change) and film softness (D value changes) values?
Is it possible to do with contact only with air?
If it can't be done in the air, how to get the values with a stable baseline? Or an unstable baseline?
4 If this logic is false, Is there another way to get a fat layer on a sensor stable in room temperature that can run water in as a baseline?
