PalmSens MultiEmstat4

The MultiEmstat4 incorporates 8 x individual Emstat4 potentiostats, each with EIS and galvanostat in a single compact chassis. The Emstat4 channels can be operated independently or in synchronised, multichannel experiments using PalmSens’s MultiTrace Software.  The system may also be used as a polypotentiostat: multiple WE’s vs one CE and RE.

Each channel is an independent Emstat4 potentiostat. Options are available for galvanic isolation (for “floating” operation. )

The MultiEmstat4 is available in either 8 channel or 12 channel versions and each of those is available in either High Range (HR) or Low Range (LR) versions.  See comparison table below.

  • Chronocoulometry (CC)
  • Multiple Amperometry (MA)
  • Pulsed Amperometric Detection (PAD)

Galvanostatic Techniques:

  • Linear Sweep Poteniometry (LSP)
  • Chronopotentiometry (CP)
  • MultiStep Potentiometry (MP)
  • Open Circuit Potentiometry (OCP)

Pulsed techniques:

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

Other

  • Mixed Mode (MM)
  • Potentiostat / Galvanostatic Impedance Spectroscopy (EIS/GEIS)

 

** Synchronizing channels in Synched mode

By enabling synchronization of channels and adjusting the setup of your cables, you can use the MultiEmStat4 as a polypotentiostat. This means you can use multiple working electrodes, one counter and one reference electrode in the same cell at the same time. Your working electrodes all perform the same measurement
