Taking flame tests one step forward: the case of a DIY atomic emission spectrophotometer

Abstract

In the present study we report the construction of a simple atomic emission spectrophotometer and we describe its computer interface and its calibration procedure. The final instrument is employed for the detection of the presence of metal ions in commercially available drugs. The cost of the whole construction is low and it can be readily applied within the secondary education chemistry curricula in order to strengthen students’ engagement and understanding of a modern analytical technique that is based on the well known flame tests.
