Atomic absorption spectrometry, inductively coupled plasma-optical emission, and inductively coupled plasma-mass spectrometry provide the most sensitive copper quantification down to parts per trillion levels. This chapter comprehensively evaluates recent advances in analytical methods for detecting copper, including atomic spectrometry, molecular spectrophotometry, electrochemical sensors, voltammetry, and chromatography. The purpose of this experiment is to determine: (1) the percentage of copper in a copper-clad penny and (2) the thickness of the copper layer on the copper-clad penny.
