electrochemistry Making a carbon paste electrode In this blog post we describe making a DIY carbon paste electrode using graphite powder/mineral oil mix and a custom-made reusable holder.
electrochemistry 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
electrochemistry 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.
electrochemistry 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
electrochemistry Cyclic voltammetry with the Rodeostat In this blog post we carried out a cyclic voltammetry experiment with ruthenium hexamine Ru(NH3)6 a reversible redox couple.
Hardware 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.
electrochemistry Cyclic voltammetry testing with the Rodeostat In this blog post we provide data from our testing of the new Rodeostat. We performed a side-by-side comparison between the Rodeostat and the Cheapstat potentiostat using ascorbate cyclic voltammetry experiments.
Hardware IO Rodeo Open Source Potentiostat We have recently been working on a new potentiostat. The Rodeostat (initally referred to as a potentiostat shield) is an open source potentiostat for performing electrochemical measurements which is designed to work with
electrochemistry Potentiostat dummy cells One of our most frequently asked questions on the Forums and via email is how to produce a calibration for the Cheapstat potentiostat. The Cheapstat potentiostat returns measured current values as raw unitless
