Description

The PalmSens3 is PalmSens’ flagship instrument and now features the option of Bluetooth connectivity to your PC or Android mobile device. The PalmSens3 is a battery powered potentiastat, galvanostat and Frequency Responce Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS) with low noise, a large potential range and high current resolution over 9 current ranges. The PalmSens3 can be used with an optional Bluetooth module (pictured above) for remote connection to a Bluetooth enabled PC or Android tablet. These features make the PalmSens3 a complete laboratory instrument, but with it’s rugged design it is also ideal for field work.

Standard Configuration

PalmSens3 is delivered with a shielded cable with connections for a working, a counter and a reference electrode by means of 2 mm banana connectors with mini-crocodile clips. The supplied testsensor is used to test the performance of the instrument. The PalmSens3 is also supplied with a USB cable for PC connection, and a copy of PSTrace included on a CD. The whole kit is supplied in a carry case making transporting the unit for field use that much easier.

PalmSens3 supported techniques

Voltammetric techniques:

  • Linear Sweep Voltammetry (LSV)
  • Differential Pulse Voltammetry (DPV)
  • Square Wave Voltammetry (SWV)
  • Normal Pulse Voltammetry (NPV)
  • ac Voltammetry (acV)
  • Cyclic Voltammetry (CV)

The above voltammetric techniques can be used for stripping voltammetry.

  • Stripping chronopotentiometry (PSA or SCP)

Technique as a function of time:

  • Amperometric Detection (AD) (Chronoamperometry)
  • Pulsed Amperometric Detection (PAD)
  • Multiple Pulse Amperometry (MPAD)
  • Fast Amperometry (FAM)
  • Potentiometry (POT)
  • Open Circuit Porentiometry (OCP)
  • Multistep Amperometry (MA)
  • Multistep Potentiometry (MP)

Impedance Spectroscopy / EIS

  • Potential scan
  • Time scan

Scans can be made at a fixed frequency or with a frequency scan.

  • Fixed potential

Extensions

PalmSens can be extended with the bipotentiostat module as well as a multiplexer with 8 or 16 channels. The opto-isolated cable, as well as the Bluetooth option, allows PalmSens to be used floating with respect to ground.
