themthem Posted December 21, 2017 Report Share Posted December 21, 2017 I needed some help in deciding a good topic for a chemistry EE. Till now I've thought of doing it in chromatography and dyes. I thought that the topic of "analysis of hair dyes was overused", so I was thinking of doing something along the lines of: "chromatography of different pen inks", or "analysis of dyes in foods such as ketchup". Thanks. Reply Link to post Share on other sites More sharing options...
