Electrochemistry: Current dependence on scan rate
In this tutorial we use the Rodeostat potentiostat and a screen printed electrode to demonstrate current dependence on scan rate. We know that for freely-diffusible analytes like ascorbate, the anodic peak current depends linearly on the square root of the scan rate. This is described by the Randles-Sevcik equation. The
Making a multichannel open colorimeter
We modified the Open Colorimeter firmware to use athe Adafruit AS7341 multichannel light sensor board.
