GC

Lab 9: Gas Chromatographic Determination of Aspirin, Tylenol, and Caffiene in Excedrin

Dr. Stephen Lukacs (September 2012)

Using a DVD player is great, but building your own, even if it is a rudimentary version, gives you whole new perspective into how it works and the level of engineering and software required to bring you that product.

A basic industrial GC costs around $25k, and a top-of-the-line GCMS costs overs $90k. In this lab, learn the techniques of development and engineering to build your own GC including the detector and computer acquisition.
