Potentiostat
Background
Nice wikipedia description of what a potentiostat is here.
A basic description of potentiostat architectures can be found at http://www.consultrsr.com/resources/pstats/design.htm
CheapStat -- PLOSOne article here -- they use a DIY design to assess ascorbic acid in orange juice, cyanide in water, acetaminophen content of over-the-counter pain medication, and arsenic in water. Neat!
An open potentiostat at Cornell is here
Uses
- Assess arsenic, cyanide, other contaminants / toxins in water
- Educational
- Identifying toxins / ingredients in foodstuffs
Development
- olm-pstat - repository for the PLOTS/PVOS Open Lab Monitor potentiostat peripheral
- source code from Jack Summers' DIY potentiostat
OHS 2013
- Table - should have power
- Device - need to try chem experiment. Craig
- Experiment materials. Craig. Two sets of cables, to avoid contamination.
- Code - realtime plot in Python. Craig
- Serial library patch
- Applications: describe what this can do. Don
- Feedback/sign up form. Ian
- Cards with logo. In a week. Jake will order.
- Schematic. Craig or Don make SVG diagram. High level and lower level of feedback loop
- Data sample image - python output, Craig
- Reference list:
- electro-chemistry textbook
- Jack
- PVOS GitHub repo
- various current publications on potentiostats
- Instructions on setup - Ian will contact Kipp. Do we get free passes as demoers, or do we need to order tickets?
- PVOS logo into Badger form - Ian
