| Abstract |
|
A laboratory exercise to be used in an undergraduate instrumental methods course is presented for the analysis of calcium, magnesium, strontium, and zinc in wisdom teeth by inductively coupled plasma–atomic emission (ICP–AES), and flame (FAA) and graphite furnace (GFAA) atomic absorption spectroscopy. In addition to exposing students to common spectroscopic instruments and reinforcing concepts taught in the classroom, the exercise demonstrates the practical application of detecting and quantifying analytes in wisdom teeth, a real-world sample. Detection limits and interferences associated with the various spectroscopic techniques are discussed. Standard additions, a technique commonly applied to account for interferences, and an error analysis associated with this technique were utilized in the analysis.
