Getting Started
Left Side
This section provides instructions for: unpacking, checking and
connecting the AE-QCM 2.0 Quartz Crystal Microbalance to its
accessories and to your experiment. Quick Start instructions are also
provided to easily perform QCM measurements.
The AE-QCM 2.0 System is a high precision mass measuring sensor
featuring excellent performances in the recovery of the beat oscillation
frequency coming from two coupled working quartz crystals. The sensor
has an integrated control electronic and it can be used standalone by
interfacing to any frequency meter, oscilloscope or any kind of
acquisition frequency system.
Sampling Head is provided with a temperature sensor and a Peltier
element for temperature control of the quartz sensor.
Resonance frequency and Temperature are measured and displayed
directly on the front panel.
In addition, the AE-QCM 2.0 has USB2.0 interface and comes with
Windows® software providing real-time display and storage of QCM
and thermal data.

Note. Once you have received the AE-QCM 2.0 system box, please immediately
contact Novaetech in order to receive AE-Software. It will be sent by email.
The AE-QCM Sampling Head can be connected to the Control Unit
by means of a cable with a Micro-D 9 PIN connector, for the
connection with Sampling Head, and a D-SUB 9 PIN connector for
the connection with the Control Unit.
AE-Software is a control and data acquisition software. By means of
AE-Software it is possible to visualize and record data coming from the
AE-QCM Sampling Head (Frequency and Sensor Temperature).
In order to prepare an AE-QCM 2.0 connection cable for your own
experiment the PIN-COLOR Table is reported.
It is also possible to control the crystal sensor temperature by driving
the built-in QCM sampling head Peltier element.
Please pay attention to the current expected on the indicated PIN useful for
the choice of the wires.

Crystal Installation
Crystal Installation
This section describes the procedure to install or replace the QCM
crystal in the Sampling Head.
AE-QCM 2.0 Quartz Crystals sensor are carefully selected by
Novaetech in order to have the best coupling with the reference crystal
mounted inside the sampling head. For this reason please
communicate the AE-QCM sampling head code reported on the heat
sink in the bottom side when you order new fresh quartz crystals.
AE-QCM 2.0 quartz crystals are mounted in Al holders for the easy
installation and replacing in the sampling head (see Figure).
Mounting and de-mounting of crystals should be always done with the
maximum care, in order to keep the crystals safe and to assure the
correct electrical contact.
The quartz sensor is correctly installed when gold electrode fits
perfectly the circular window on the up side if the sampling head.
In order to avoid frequency noise do not touch sensor holder during the
measurement operations.
In any case do not force the insertion of quartz crystal in the
sampling head.
It is suggested not to replace a sensor crystal until the saturation
is reached.

QCM Measurements
QCM Measurements
The first use of QCMs was as mass sensors and thickness monitors in
gas phase, thin-film depositions. To this date, this continues to be an
important area of application for this technology.
Sauerbrey Equation
Sauerbreyʼs equation is often used to calculate mass loadings and thinfilm thicknesses in vacuum depositions. The basic assumption is that
the incremental change in mass from the foreign film is treated as
though it were really an extension of the thickness of the underlying
quartz. The foreign film is considered rigid and so thin that it does not
experience any shear forces during vibration. As a result, the sensitivity
factor, S, is a fundamental property of the quartz crystal and does not
consider any of the properties of the foreign film (i.e. it is only
dependent on the acousto-elastic properties of quartz).
The dependence of the frequency change on the mass coverage per
unit area, emphasizes the fact that, within certain limits, the sensitivity
factor is independent of the electrode geometry. Thus, in theory, the
QCM mass sensor does not require calibration for this application. This
ability to calculate mass loading from first principles is obviously a very
attractive feature of these devices.
Film thickness
Film thickness is often the parameter of interest in gas-phase thin-film
depositions. If the mass coverage is believed to be uniform, the
thickness t of the film is easily calculated by dividing the mass per unit
area M provided by Sauerbreyʼs equation by the materialʼs density #.
By means of Sauerbray Equation mass per unit area M in function of
resonance Frequency shift !" (S is crystal sensitivity):
