PalmSens3 battery replacement
The following procedure describes how to replace the battery on your PalmSens3.
PalmSens3 recovery
This article guides you on how to recover your PalmSens3 firmware if it does not connect properly anymore using a USB cable or wirelessly.
Voltammogram
A voltammogram is a graph that can be drawn after an electrochemical experiment. This graph has a typical, recognizable form in which the electron flow (current: i) is measured in Volt against the potential (E).
Redox Potential
Redox potential (reduction potential of ORP) is an abbreviation for reduction and oxidation potential. A redox potential is the potential value when the reduction and oxidation of a certain metal or other chemical are in balance with each other. Redox potential is measured in Volt (V).
Future of electrochemical sensors
Curious how electrochemical sensors will be used in the future? Niels van Velzen, the CTO of PalmSens, explains about biosensor strips and portable readers. The readers perform mea...
Portable potentiostat
In some cases you want to carry out your measurements in the field, in several places and have results available immediately. That is why PalmSens has developed a portable battery-powered potentiostat and a USB-powered potentiostat that you can connect directly to your phone.
Potential
A potential is nothing other than the voltage or electrical voltage of a specific (liquid) substance.
Impedance analyzer
An impedance analyzer is a device that can measure how a particular substance or electrode surface responds to a a potential that is constantly increased and decreased within certain predefined limits (a potential wave).
Galvanostat
If you want to apply a current to a liquid, such as mercury, and want to observe the change of potential, you need a device that can control the former and measure the latter. Such a device is called a galvanostat.
Frequency response analyzer
Nowadays, potentiostats are usually equipped with a frequency response analyzer so that you only need one device for the entire experimental setup. If you need a frequency response analyzer, the purchase of a PalmSens4 portable potentiostat is your best choice.
EIS Analyzer
An EIS Analyzer is a device that can measure how a particular substance or electrode surface responds to a a potential that is constantly increased and decreased within certain predefined limits (a potential wave).
Electrochemical Impedance Spectroscopy (EIS)
Electrochemical Impedance Spectroscopy (EIS) is an electrochemical technique to measure the impedance of a system in dependence of the AC potentials frequency.
Economical Potentiostat
If you want to do electrochemical measurements with a specific purpose in mind, you may need an economically priced potentiostat. Palmsens has several attractively priced instruments for you.
Cyclic voltammetry
Cyclic voltammetry is a known method of demonstrating the presence of a substance in a given liquid by drawing a graph with a characteristic wavy line. The graph has a typical, recognizable form in which the electron flow (current: i) is measured in Volt against the potential (E).
