Square wave anodic stripping voltammetry and metal testing
The Rodeostat python library has several electrochemistry programs currently implemented including cyclic voltammetry, constant voltage, linear sweep, chronoamperometry and more. We have recently added a square wave anodic stripping voltammetry (SWASV) program to the library. Stripping voltammetry is a powerful electroanalytical technique for the detection of trace metals in the
Electrophoresis power supply - LCD display
We have recently updated the electrophoresis power supply
[https://iorodeo.com/products/electrophoresis-power-supply] to include an LCD
display as shown in the images below. The price of the power supply kits remains
the same ($65 for a kit). We also have a fully assembled and ready-to-use power
supply option for
Making a custom electrochemical cell
In this blog post we describe making a simple custom electrode mount that we used in cyclic voltammetry experiments with the Rodeostat potentiostat. The electrodes we used were purchased from CH Instruments but the custom mount could be easily modified for use with other electrodes.
Chronoamperometry with glucose test strips
In this electrochemistry experiment we used the Rodeostat potentiostat to measure glucose in liquids using commonly available glucose test strips. Glucose test strips are a type of biosensor - they convert biochemical reactions to an electrochemical signal. Each glucose test strip contains the enzyme glucose oxidase (GOx) and an electron
Reversible Cyclic Voltammetry
In this blog post we carried out a cyclic voltammetry experiment with ruthenium hexamine Ru(NH3)6 a reversible redox couple.
Open source potentiostat features
In this blog post we give a quick overview of some of the main differences between two open source potentiostats: Rodeostat and Cheapstat.
