  • Page 7: Introduction

    ,1752'8&7,21 The Princeton Applied Research PARSTAT 2273 offers compliance voltage up to ±100 V (available at the counter electrode), ±10-V scan ranges, a ±2-A current range, the ability to make electrochemical impedance spectroscopy (EIS) measurements from 10 µHz to 1 MHz, and a design that will sustain long-term, heavy-load operation.

  • Page 8: Booster Interface

    direct methanol fuel cell (DMFC) assemblies. The 2273 together with the entire Electrochemistry PowerSuite package has the potential to take your research to the next level. Biomedical Applications — The 2273 exceeds the requirements for potentiostats/galvanostats as described in ASTM F2129, Standard Test Method for Conducting Cyclic Potentiodynamic Polarization Measurements to Determine the Corrosion Susceptibility of Small Implant Devices.

  • Page 9: Galvanostatic Mode

    Fig. 1. Potentiostat-Mode Block Diagram. 1.4.2. Galvanostatic Mode In galvanostatic operation, the PARSTAT 2273 controls the current between the counter and working electrodes at the specified fraction of the selected current range (up to the maximum of 100% the current range; see Fig. 2). The counter electrode is driven to the potential required (consistent with the ±100 V compliance of the control amplifier) to establish the desired cell current.

    equilibrium potential, the resulting current is anodic. If the electrode is driven negative with respect to the equilibrium potential, the resulting current is cathodic. In complex electrochemical systems, there might be more than one equilibrium system. Where this is the case, either polarity with respect to the equilibrium potential could give rise to anodic or cathodic current, according to the system’s characteristics.

    1. Disconnect the instrument from the ac power source. 2. Use a small flat-blade screwdriver or similar tool to pop open the module door. 3. Remove the plastic drum — pinch the sides of the drum with your fingernails and pull, or insert a flat- blade screwdriver in the slot between the 120Vac and 240Vac settings and gently pry the drum loose, one end at a time.

    2.3. Defects and Abnormal Stresses WARNING If your instrument has been damaged, its protective grounding might not work. Do not operate damaged equipment! Tag it to indicate to a potential user that it is unsafe to operate. The PARSTAT 2273’s ground protection is likely to be impaired if, for example, the instrument: Shows visible damage.

  • Page 14: Transient Sensitivity

    WARNING To reduce the risk of potentially dangerous electrical shock, only a qualified service technician should perform this work, and then only with the instrument disconnected from all sources of power. At frequencies above 10 MHz, these measures might not suffice to prevent radiation from being a problem, particularly at VHF frequencies.
  • Page 15 Static discharge problems can sometimes be avoided by judiciously selecting the floor covering in the work area. The simplest approach to the problem is to discharge your body by touching a grounded metal object just before touching the instrument, particularly when making connections to the cell.

    Interface. AUXILIARY INTERFACE can also turn the Model 616 Rotating Disk Electrode on and off with the STIR signal issued within Electrochemistry PowerSuite. See Section 4.4 for the pin assignments. USB — Attach the supplied USB cable (part no. 752860) to this connector and to the USB connector on the PC.

    I-MON — Rear-panel BNC accepts signal indicating the current being provided by the Power Booster. NORMAL — Switches between BOOSTER mode and NORMAL (unboosted) mode. If you wish to use the 2273 without the Power Booster, disconnect the cell cable from the Power Booster and connect the standard 2273 cell cable to the 2273 front panel.

  • Page 20: Controls

    DANGER Potentials as high as ±100 V at currents as high as 2 A could be present at the counter electrode lead of the cell cable. The CELL ON indicator should always be off (unlit) when making the cell connections, as well as when the cable leads are being examined or disconnected.

    3.3. Connecting to the PC and Cell This section tells you how to connect the PARSTAT 2273 to the host PC and electrochemical cell, and to other equipment you might wish to use with it. WARNING For operator and equipment safety, power to all instruments should be off when connecting or disconnecting cables.
