Scanning micro-electrode workstation can be used to monitor or impose current flowing between a micro-electrode and a specimen surface in solution
Uniscan Instruments, a specialist manufacturer of electrochemical and surface measurement instrumentation, has recently introduced the SECM270 scanning electrochemical microscope, complementing its line of surface imaging systems.
The Uniscan SECM270 is a scanning micro-electrode workstation, which can be used to monitor (or impose) current flowing between a micro-electrode and a specimen surface in solution.
It is used to examine, analyse, or alter the surface chemistry of a sample at high resolution and has many potential applications in the study of fundamentals of surface reactions for example in corrosion science, or the study of enzyme stabilisation and Mems.
The design specification of the Uniscan SECM270 includes an integrated bi-potentiostat used in conjunction with a high precision scanning micro-electrode system.
All scanning parameters, variables, control, data acquisition and post data acquisition analysis are performed on a PC via a direct, single connection to the parallel (printer) port.
The probe scanning system incorporates closed loop direct motor drive to all (x, y, and z) axes with absolute probe position being measured by linear encoders on each axis.
Using Uniscan's proven, powerful and user friendly software, all scan cycles are automated and are user definable, including linescan, repeat linescan, z-approach scan, and area map scan, as well as standard electrochemical analysis techniques.
