The Quartz Crystal Microbalance QCMagic (QCM) set-up
has been designed to directly drive piezoelectric transducers. It
consists of single/multiple measuring units, driven by a PCI
interface, suitable for:
-
biosensor development
-
affinity reaction studies
-
association/dissociation and kinetic
constants determination
-
monoclonal antibodies
characterization
-
binding site mapping
-
DNA hybridization
-
analysis of electrochemical
deposition, polymers coated on electrodes, corrosion, adsorption
and electrochemical reaction mechanisms
-
multi-probing detection
QCMagic is a high precision measuring instrument
featuring excellent performance in the recovery of the oscillation
frequency of a working quartz crystal.The system is interfaced to
the driving PC by means of a digital counter PCI board. One single
PCI board can drive up to 4 oscillator Units, thus allowing to
operate with up to 4 independent quartz crystal (or with two pairs
of working/reference crystals). QCMagic can be equipped with
low-volume static or flow-through reaction chambers, which house the
oscillating crystal; fitting the transducer into the different type
of cells is rapid and convenient. QCMagic makes use of a precision
internal reference crystal, used as a timebase comparator. Depending
on the frequency of this internal timebase, each Unit can be tuned
to work with a specific working crystal, choosen between 1 and 10
MHz. When more Units are used, they are cross-connected by means of
one single cable carrying both power supply and signals. |
