Quartz Cystal Microbalance QCM-i QCM-D eQCM
Quartz Crystal Microbalance (QCM) is an instrument that allows a user to monitor small mass changes on the surface of a coated quartz crystal. Gamry’s line of Quartz Crystal Microbalance instruments include high-sensitivity mass sensors which measure frequency and dissipation while giving you the option to simultaneously run electrochemical experiments to gain insight into what drives mass changes within films.
QCM-I QUARTZ CRYSTAL MICROBALANCE.
WITH DISSIPATION (QCM-D)
The QCM-I measures changes in frequency and dissipation of a quartz crystal resonator using a vector network analyzer. By sweeping the frequency around the fundamental frequency and its overtones, you get both frequency changes and dissipation changes. When the qcm sensor acts as a biosensor, it gives a “wet mass’ of the adsorbed layer for processes occurring at or near the sensor surface.
Features:
- Monitors both frequency and dissipation
- Multiple harmonics (up to the 13th overtone for 5 MHz crystals)
- Temperature control from 4°C to 80°C (± 0.02 °C) is included
- Optional electrochemical measurement module
- Modular sensor holder up to 4 measuring channels (two channels standard)
- External PC with Windows® 10; communication with QCM-I via USB
Standard Dissipation Sensitivity in Liquid ~ 1 x 10-7
QCM-I MINI QUARTZ CRYSTAL MICROBALANCE.
WITH DISSIPATION (QCMD)
The QCM-I Mini qcm sensor measuring principle is identical to the QCM-I in that a vector network analyzer is used to monitor changes and frequency and dissipation of the quartz crystal and films on its surface. QCMs are useful in any number of applications – biosensors, chemical sensors, corrosion, polymer films, nanoparticle films, etc.
Features
- Monitors both frequency and dissipation
- Multiple overtones (up to the 13th for 5 MHz Crystals) can be quickly and sequentially measured
- Temperature control from 15° C to 60° (± 0.02° C) in included on one channel
- Two independently measured channels
- External PC with Windows® 10 Communication with QCM-I Mini via USB
Standard Dissipation Sensitivity in Liquid ~ 1 x 10-7
EQCM-I MINI QUARTZ CRYSTAL MICROBALANCE.
WITH DISSIPATION (QCMD)
The eQCM-I Mini qcm sensor is useful in any number of applications by combining electrochemical measurements with mass measurements to gain further insight into what drives mass changes within films. Electrochemical measurements are performed by coupling a potentiostat to the QCM and controlling the potential of the electrode on the surface of the crystal.
Features:
- Monitors both frequency and dissipation
- Multiple overtones (up to the 13th for 5 MHz crystals) can be quickly and sequentially measured
- Integrated with Gamry USB-based potentiostats
- Temperature control from 15° C to 60° (± 0.02° C) in included on one channel
- Two independently measured channels
- External PC with Windows® 10; communication with QCM-I via USB
Standard Dissipation Sensitivity in Liquid ~ 1 x 10-7
