PalmSens3 is a battery-powered potentiostat / galvanostat with optional impedance analysis (EIS) which offers all the common voltammetric and amperometric techniques as described in the PSTrace software documentation. New techniques are added regularly so, if you do not see the technique you need please let us know – it may be newly available or we may be able to add it in the next release.
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.
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
- 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
Scans can be made at a fixed frequency or with a frequency scan.
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.
