Flame Atomic Absorption

Flame Atomic Absorption is a technique used to analyze the concentration of specific elements in a sample, such as metals in water or soil. The sample is sprayed into a flame, where it gets heated and the atoms of the element of interest become energized. A light beam with a wavelength specific to that element passes through the flame. If the element is present, it absorbs some of the light, and this absorption is measured. The amount of absorbed light correlates directly with the element's concentration, allowing precise quantitative analysis.
