Water Quality 2 - Determination of Ca, Mg, Fe, and Na by Flame Atomic Spectrophotometry Introduction Atomic spectroscopy is one of the most widely used methods for quantitative elemental analysis. There are a number of situations where elemental composition is important , how much iron in an ore sample, how much lead in your drinking water, calcium in intracellular fluids. In a sense, it s the simplest type of analysis, since there are only about 120 possible analytes. But to do the analysis, the sample has to be completely destroyed (chemically and physically) and reduced to individual gas phase atoms (or related species, like ions) in well defined states that you can do spectroscopy on.
the colorimetric complexation reaction / spectrophotometric determination used in the other experiment of this set. You will thus use the same calibration set and unknowns as you did in the previous experiment (without the colorimetric reagent, buffer, and hydroxylamine) to facilitate a head-to-head comparison of the two methods.
