Description

The EmStat3+ is a research grade potentiostat that was initially developed for OEM purposes. The EmStat3+ is a reliable and versatile potentiostat that found it’s way to the market in many  different forms. 

The EmStat3+ module is successfully integrated in devices for specific applications, but also in our own product range that we sell for generic research purposes such as the EmStat Blue, EmStat Go and MultiEmStat. The main difference between the EmStat3 and EmStat3+ is the extra current range of 100 mA for the EmStat3+ module.

When only one module is added in the basket we will quote the EmStat3+ Starter Kit which includes all the components you  need for rapid prototyping and hardware validation.

Techniques

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.

Techniques as a function of time:

  • Chronoamperometry (CA)
  • Pulsed Amperometric Detection (PAD)
  • Multiple Pulse Amperometry (MPAD)
  • Open Circuit Potentiometry (OCP)

Specifications

The EmStat module features:

  • 9 embedded common electrochemical techniques
  • options for manual cell control (potentials, changing current range and timing)
  • USB and serial communication or USB as Virtual COM port
  • automatic current ranging
  • digital I/O for peripheral control (stirrer or valve)
  • analog input for measuring auxiliary input like temperature
  • analog output for controlling peripherals like a stirrer
  • multiplexer control

EmStat3 and EmStat3+ are also available as stand-alone instrument for research or OEM evaluation.

Software

The EmStat module can be used with our PSTrace software for Windows. This allows you to evaluate its capabilities before starting your development project.

Software can be developed in any language or for any platform by means of the EmStat Communication protocol. A C library which implements the EmStat Communication protocol is also available. Other available code example and libraries include:

  • .NET (WinForms and UWP)
  • Matlab
  • Arduino

Embedded SDK for EmStat3 An example project of how to use the SDK is provided for Arduino. It's made in "Arduino Software (IDE)" found at "www.arduino.cc". For more information about the example, read the comments in "EmStatSDKExample.ino". A short explanation with an example of how to use the SDK in any c/c++ environment can be found in PSComm.h. The Arduino example should also be easy to port to C or C++, if required. For more advanced use beyond the scope of the SDK, refer to the "EmStat communication protocol##.pdf".09-04-20
