ChromatograDIY: Open-Source Chromatography Effort

Richard Arnett

$2,400Next Goal
This project was funded on:
3 April 2014
ChromatograDIY is a Gas Chromatograph I am building from scratch. I am using open-source firmware and software for electronic equipment control/data acquisition such as Arduino-based micro-controllers and OpenChrom software. I am documenting all the steps I take to achieve this on the blog ChromatograDIY. Parts manufactured are built at the non-profit makerspace TX/Rx Labs in Houston, where I am a member with a rented workspace.


Budget Overview

All funding will go towards purchasing parts from which the chromatograph will be assembled.

Most of the circuit boards will be purchased from Adafruit, they have an extensive supply of boards and parts. Almost every part comes with tutorials and everything is open-source. Other sites that are just as important for this project are are and Github.

One month of membership (including dedicated workbench) is being included as I do ALL my work at the greatest makerspace/hackerspace in Houston: TX/Rx Labs A Stretch Goal has been added to support the building of a 2nd prototype instead of just one since the 2nd Goal will be to give a GC to a local college for validation work.
