Description

EmStat Blue is a small and low cost potentiostat with research grade capabilities. It has eight current ranges from 1 nA to 100 mA (EmStat3+ Blue) full scale, with a minimum resolution of 1 pA. It provides the most relevant electroanalytical measurement techniques and is used with the PSTrace software or with PStouch for Android.

Standard included with an EmStat Blue:

  • Rugged carrying case
  • High quality, double shielded cell cable with
    2 mm banana connectors for Working, Counter, Reference electrode and Ground
  • Crocodile clips
  • Dummy cell
  • USB cable
  • PSTrace software for Windows

Optional:

  • Samsung tablet for use with PStouch

Sensor cable with croc clips

 

Customization for (industrial) applications

The EmStat Go potentiostat is very similar to the EmStat3 Blue and can easily be taylored and re-branded for end-user applications.

Techniques

The following techniques are supported by EmStat Blue.

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)
  • Multistep amperometry (MA)
