QCM-soft is a set of four different programs dedicated to different types of measurements using QCM technique. It works together with QCM-3. QCM-soft is the result of more than 10 years of continuous development, closely related to different measurements performed with earlier versions QCM-1 and QCM-2 as data aquisition boards plugged into a PC.
QCM-soft has a user-friendly concept allowing the widest range of measurements based on the QCM  technique.

QCM-soft includes the following programs:

1.  Dual Quartz Crystal Microbalance
2.  Differential Quartz Crystal Microbalance
3.  Thermocompensated Quartz Crystal Microbalance
4.  Current Compensated Quartz Crystal Microbalance

Dual Quartz Crystal Microbalance is a program which allows simultaneous measurements with two different quartz crystal resonators.

Differential Quartz Crystal Microbalance is a program which allows the possibility for differential measurements. Thus, the spurious effects of the temperature, pressure, air and liquid viscosity are greatly reduced or even eliminated. The accuracy of the QCM measurements is significantly improved using this program.

Thermocompensated Quartz Crystal Microbalance is a program which allows mass measurements within a wide temperature range using a commercial quartz resonator and a temperature sensor (Pt-1000) placed closed to the quartz resonator. Performing a slow sweep of the temperature in the desired temperature range a data-base including the frequency-temperature characteristics of the used resonator is created. When mass measurement experiments are performed the frequency-temperature characteristics of the used quartz resonator is subtracted from the total frequency change, revealing thus the net mass effect.

Current Compensated Quartz Crystal Microbalance is a program based on the same concept as Thermocompensated Quartz Crystal Microbalance but, instead of a temperature sweep, the crystal current is swept within the desired range. The amplitude-frequency effect is thus eliminated. This program is useful when the effect of the acceleration on the deposited films is investigated.

The possibilities of the QCM-soft can be directly evaluated by free download of the QCM-soft. This is the real program, not a demo.
