Development of a Handmade Fluorometer and Proposals for its Application in Practical Courses of Instrumental Analytical Chemistry in the Graduation

This work proposes the development and use of a homemade fluorimeter from electric/electronic low cost materials and scraps, as a didactic resource for motivating the investigation of the fluorescence phenomena in analytical chemistry courses. Some tasks about quinine using this craft are also proposed, such as, analysis of excitation and emission spectra so that the student can learn how to set the best wavelengths to perform quantitative measurements, studies of pH changes and halide ions effects on its fluorescence signal. The developed equipment is very simple allowing the student to understand the principles involved on its construction.
