Emission spectroscopy provides an effective analytical technique as both a survey method and as a quantitative analysis tool. The principles and system components of the technique are described. The sample types, sensitivity, concentration ranges, and precision and accuracy allow traces of most elements to be detected in solids, liquids or gases. The steps of a quantitative method are outlined. Emission spectroscopy finds applications in the analysis of biological tissues and fluids, water sampling, and the analysis of air samples. Up to 19 minor elements can be detected at concentrations below the parts per million range.
