Uniscan Instruments has launched a new concept in scanning probe electrochemistry instrumentation with the introduction of the model 370 scanning electrochemical workstation
For the first time, users will be able to have access to all the major scanning probe electrochemical techniques with one modular system.
The M370 can be configured to the users choice with any or all of the following techniques: scanning electrochemical microscopy [SECM] scanning vibrating electrode technique [Svet] scanning Kelvin probe [SKP] localised electrochemical impedance [LEIS].
The scanning electrochemical microscopy technique [SECM] is particular suited to the investigation of electrochemical phenomenon at the tip of a micro probe or at the surface of the material under investigation.
It can be used to examine, analyse or alter the surface chemistry of a sample in solution.
The scanning vibrating electrode technique [Svet] has its beginnings in the technique used in the investigation of corrosion phenomenon more than 60 years.
Its use for the monitoring of living cells was investigated more than 30 years ago.
The scanning vibrating electrode technique (Svet) operates with a non-intrusive scanning, vibrating probe measuring and mapping the electric field generated in a plane above the surface of an electrochemically active sample.
This enables the user to map and quantify local electrochemical and corrosion events in real time.
The scanning Kelvin probe technique [SKP] is a non-contact, non-destructive measurement between conducting, coated, or semi-conducting materials and a metallic probe.
The scanning Kelvin probe has its roots in an experiment conceived more than 100 years ago by Sir William Thomson, later to be known as Lord Kelvin.
This instrument brings to the laboratory the power of the technique coupled with an easy to use software interface.
The localised electrochemical impedance technique [LEIS] allows spatially resolved impedance measurements to be made, combining established principles of EIS measurements with scanning probe technology.
The principles of LEIS are similar to those employed in traditional bulk EIS, but by combining an existing bulk impedance system, consisting of a potentiostat and phase sensitive detector, allow the user the pinpoint an area of electrochemical activity.
The Uniscan Instruments model M370 workstation is available with a wide range of optional probes, cells and accessories.
