QCM-I 石英晶体微天平

with Impedance Measurement and Dissipation

QCM-ITM Quartz Crystal Microbalance is a high-sensitivity mass sensor which measures the change in frequency and dissipation of a quartz crystal resonator and any adsorbed film.  QCMs are useful in any number of applications - biosensors, chemical sensors, corrosion, polymer films, nanoparticle films, etc. Changes in frequency as well as dissipation give information relating to changes in mass or elasticity of films. 

The QCM-I, QCM-I Mini, and eQCM-I Mini are manufactured by MicroVacuum Ltd. (http://www.owls-sensors.com/) of Budapest, Hungary. MicroVacuum has integrated control of our USB-based potentiostats into their BioSense software (V3 or higher). Gamry has partnered with MicroVacuum for distribution of these instruments in the United States and China. Inquiries outside of the US and China can go directly to MicroVacuum (http://www.owls-sensors.com/contactus). 

The measuring principle is based on impedance analysis of the quartz crystal. The resonant frequency and the bandwidth of the resonant conductance curve are determined. The bandwidth or full width at half maximum, (FWHM) is a direct correlation with the quality factor (Q) which is by definition the inverse of dissipation (D).

QCM-I Features:

·         Both the frequency and the quality of resonance (FWHM or bandwidth or dissipation) are measured

·         Different harmonics (up to the 13th overtone at 5MHz crystals) can be quickly and sequentially measured

·         Temperature control from 4°C to 80°C (± 0,02 °C) is included

·         EC measurement module is optionally available with ITO-QCM sensors

·         Modular sensor holder up to 4 measuring channels

·         External PC with Windows® 10; communication with QCM-I via USB

 The software performs full control of the QCM-I Instrument.  Two measurement modes are available:

1.    Resonance:  Measurement of resonance curve and calculation of the resonance frequency & FWHM up to 70 MHz

2.    QCM-t:  Continuous measurement of the resonance parameters and the temperature of the flow-cell.

Calculation:  Various QCM and ad-layer parameters can be calculated using standard or custom made models.  All these parameters can be displayed on the screen, printed, saved or can be exported for further evaluation.

What's Included:

·         QCM Unit with two temperature controlled channels

·         PC Computer INTEL NUC with Windows® 10 Pro

·         QCM Sensor Holder (flow through type) 2 pc

·         BioSense 3.xx Software (one user license)

·         Sample Injection System with Semi-automatic injection valve
