Product Description

Our flagship instrument, the PalmSens4, is a USB and battery powered Potentiostat, Galvanostat, and optional a Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS). The PalmSens4 has a large potential range (-5V to 5V or -10V to 10V) and current range (100 pA to 10 mA) with a high resolution and low noise. This instrument is a complete laboratory instrument but its compact and rugged design makes it also ideal for field work.

Available Configurations

The PalmSens4 is available with ±5V or ±10V DC-potential ranges and with different maximum frequencies for FRA / EIS. The following table shows the applicable product codes:

  DC-Potential Range of ±5V
DC-Potential Range of ±10V
NO EIS [F0] (see PalmSens3) PS4.F0.10
EIS up to 100 kHz [F1] PS4.F1.05 PS4.F1.10
EIS up to 1 MHz [F2] PS4.F2.05 PS4.F2.10


Standard included with a PalmSens4:

  • high quality, double shielded cell cable
  • 2 mm banana connectors for working, counter, reference electrode and ground
  • mini-crocodile clips
  • USB cable
  • Dummy cell
  • software



Voltammetric techniques:

  • Linear Sweep Voltammetry (LSV)
  • Differential Pulse Voltammetry (DPV)
  • Square Wave Voltammetry (SWV)
  • Normal Pulse Voltammetry (NPV)

  • Cyclic Voltammetry (CV)

These methods can all be used in their stripping modes which are applied for (ultra-) trace analysis.

  • Stripping chronopotentiometry (PSA or SCP)

Technique as a function of time:

  • Chronoamperometry (CA)
  • Pulsed Amperometric Detection (PAD)
  • Multiple Pulse Amperometry (MPAD)
  • Fast amperometry (FAM)
  • Chronopotentiometry (CP)
  • Open Circuit Potentiometry (OCP)
  • Multistep Amperometry (MA)
  • Multistep Potentiometry (MP)
  • Mixed Mode (MM)

Impedance spectroscopy / EIS:

  • Potential scan
  • Time scan

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

  • Fixed potential
