AAS involves several key components: a light source, a sample holder, a monochromator, and a detector. The light source, typically a hollow cathode lamp, emits light at a wavelength specific to the element being analyzed. The sample, often in solution form, is atomized in a flame or graphite furnace. The monochromator isolates the specific wavelength of interest, and the detector measures the amount of light absorbed by the sample. This data is then used to calculate the concentration of the element.
