Dimension Electrochemistry Hardware

In addition to an EC-capable microscope, EC requires the following hardware components:

• EC Chuck
• Dimension General Purpose Electrochemistry Cell which replaced the Dimension Electrochemistry Cell.
• Appropriate probe holders:
  • ScanAsyst/Contact Mode EC Probe Holder used with the Dimension General Purpose Electrochemistry Cell.
  • TappingMode EC Probe Holder used with the Dimension General Purpose Electrochemistry Cell.
  • High Efficiency Direct Drive TappingMode Fluid Probe Holder (High Efficiency Direct Drive TappingMode Cantilever Holder, DTFML-DD-HE) used with the Dimension Electrochemistry Cell.
• Potentiostat
• EC Multiplexer
• Electrodes:
  • Electrodes for the General Purpose Electrochemistry Cell
  • Electrodes for the Electrochemistry Cell
• Lakeshore Temperature Controller (optional):
  • LakeShore 331S Temperature Controller
  • LakeShore 335 Temperature Controller
• MBraun Glovebox (optional)

The system diagram for the Dimension Icon Electrochemistry Cell with heating is shown in Figure 1.

Figure 1: Dimension Electrochemistry System block diagram

The electrochemistry (EC) cell magnetically attaches to the Dimension Icon EC chuck. The EC electrical connections are made through the EC chuck base and spring terminals on the EC chuck. These spring terminals are connected to the DB15 cable that exits the left side of the chuck. The Dimension Icon EC Chuck incorporates a heating element (ambient to 60°C) with two temperature sensors. One sensor is built into the chuck and is used for controlling the chuck temperature. An external sensor is provided to calibrate the temperature drop from the controlling temperature sensor (A) to the sample. The temperature sensors and chuck heating element are connected to the DB-15 cable that exits the left side of the chuck. The Dimension Icon EC Extension cable connects to the DB-15 chuck connector. In Dimension Icon systems with an acoustic hood, the cable exits the acoustic hood through the left cable clamp and connects to the EC Multiplexer (Mux) Box. The EC Mux Box cables connect to the LakeShore temperature controller for controlling the EC chuck temperature and also a DB9 cable which has the EC cell signals to route to a user supplied potentiostat.
