Scanning Electrochemical Workstation Software

The Scanning Electrochemical Workstation software provides unique capabilities and interactivity in support of the Model 370 and Model 470 nanometre-resolution scanning probe microscopes. The software is designed with the user in mind:

  • To enhance data analysis, manipulation and interactivity.
  • To ease research by automating measurements and sequencing.

Over 40 discrete experiments provided throughout, each with their own individual variations such as:

  • Height-Tracking (above surface)
  • Surface-Tracking (on surface)
  • Step Scan
  • Sweep Scan
  • Pre-Delays, Line-Delays, Velocities, Step Sizes, Scan Dimensions, Signal Conditioning Parameters, Control Loop Parameters, Potentiostat Setting etc.

 

The Software provides both 64bit and 32bit WindowsTM support in a standard Multiple Document Interface (MDI) application that supports all standard WindowsTM features.

The Software is completely self-contained in a single application, and contains:

M370 M470
• Electrochemistry suite (EChem)
• Corrosion suite (ECorr)
• Scanning Electrochemical Microscopy (SECM)
• alternating-current Scanning Electrochemical Microscopy (ac-SECM)
• intermittent-contact Scanning Electrochemical Microscopy (ic-SECM)
• combined ic-ac Scanning Electrochemical Microscopy (ic-ac-SECM)
• Scanning Vibrating Electrode (SVET)
• Scanning Kelvin Probe (SKP)
• Capacitive Height Measurement/Tracking  (CHM / CTM)
• Localised Electrochemical Impedance Spectroscopy  (LEIS)
• Scanning Droplet System / Cell  (SDS / SDC)
• alternating-current Scanning Droplet System/ Cell  (ac-SDS / ac-SDC)
• Non-contact Optical Surface Profiling (Laser based)  (OSP)

3DMaps2

  • Experiment Sequencing.
  • Multiple views of the same data presented in different formats or presentations.
  • User-definable presentations of the data through a simple template-design tool.
  • Fully programmable macro language for non-standard experiments.
  • Relieve sample topography in area maps using “Height Tracking” from any topography data source: CHM, CTM, OSP, constant current SECM and ic-SECM.
  • Direct real-time readout of displacement in x, y and z.
  • Surface maps acquired at up to 70,000 data points in each axis.
  • Simultaneous acquisition of multiple parameters at each point; 1 scan = many maps.
  • Up to 12 different area maps populated simultaneously in a single scan, with 4 additional maps reserved for users’ data analysis.
  • Application preferences for current convention.
  • Application preferences for graph visuals.
