Reverse Normal Pulse Voltammetry
Reverse Normal Pulse Voltammetry is an electrochemical technique, usually called Normal Pulse Voltammetry at PalmSens. With Reverse Normal Pulse Voltammetry the influence of diffusion limitation on your I-E curve (Cottrel behavior) is removed.
Pot. Differential Pulse
Pot. Differential Pulse is an electrochemical technique commonly called Differential Pulse Voltammetry at PalmSens.
Differential Pulse Polarography
Differential Pulse Polarography is an electrochemical technique commonly called Differential Pulse Voltammetry at PalmSens. ...
Amperometric Detection
Amperiometric Detection or Chronoamperometry (CA) is a simple, widely used electrochemical measurement technique. Many sensors, like those for glucose or oxygen, require this technique.
Potentiometric stripping analysis
Potentiometric stripping analysis is a sensitive analytical technique. Before the SCP measurement starts a deposition stage at the deposition potential E dep is required. After th...
Chrono methods high speed (∆t > 100 ns)
Chrono methods high speed (∆t > 100 ns) is a form of amperometric detection with very high sampling rates or respectively very short interval times. At PalmSens is is better k...
Chrono methods (∆t > 1 ms)
Chrono methods (∆t > 1 ms) or Amperiometric Detection is a simple, widely used electrochemical measurement technique. At PalmSens it is better known under the name Chronoamper...
BiPotentiostat
A BiPotentiostat is a potentiostat with two working electrodes. One electrode is the counter electrode and the other is the reference electrode. The two working electrodes can be operated and monitored exactly simultaneously. A Bipotentiostat is sometimes called a BiPot.
Square Wave Voltammetry (SWV)
Square Wave Voltammetry (SWW) is in fact a special version of Differential Pulse Voltammerty (DPV). Differential Pulse Voltammetry is Square Wave Voltammetry when t pulse is equal ...
The equations behind the potentiostat
This article explains the working of a potentiostat more in depth, using Faraday’s law and the Nernst equation. For the basics of the potentiostat, please read the potentiost...
MethodSCRIPT in action: introduction, demonstration and Q&A session
As an OEM supplier, PalmSens is aware of how important your own software is. We support our customers with several Software Development Kits (SDK), which make writing your own sof...
Multi-channel potentiostat
Do you want to perform several electrochemical measurements simultaneously? Then you need a multi-channel potentiostat. A multichannel potentiostat allows you to perform multiple experiments at the same time.
Electrochemistry in 25 minutes
In 25 minutes, you can learn what electrochemistry is, get a few example applications and learn how you can build you own electrochemical reader. After an electrochemical wine tas...
2, 3 and 4-Electrode System & Sense Lead
Sense leads also known as working sense leads are common for many potentiostat brands. PalmSens uses the Sense lead on all models that can supply 100 mA or more. This raises the qu...
Demonstration of Nitrate Measurements
Plants are using nutrition from soil to grow. If we harvest plants and transport them to a different place, for example, a market, we remove nutrition from the soil. The soil will...
Linear Sweep Voltammetry (LSV)
Linear Sweep Voltammetry is also known as Linear Polarization. In Linear Sweep Voltammetry a potential scan is performed from the begin potential, E begin, to the end potential E e...
Time scan
Time scan usually refers to an AC (Alternate Current) measurement where the frequency is fixed, and the Impedance is measured versus time. Sometimes it is called as “Time Sca...
EIS potential scan or current scan
EIS Potential scan or current scan is an electrochemical technique that can be applied with any EIS-capable PalmSens potentiostat. ‘E dc scan’ means that multiple measu...
