Always a backup of your data with 8 GB of internal storage
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.
Techniques:
Voltammetric techniques:
Linear Sweep Voltammetry (LSV)
Differential Pulse Voltammetry (DPV)
Square Wave Voltammetry (SWV)
Normal Pulse Voltammetry (NPV)
AC Voltammetry (ACV)
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)
