Flame in atomic absorption spectroscopy
WebAtomic emission spectroscopy (AES) is a convenient method for the determination of alkali metals in water samples. These metals are easily excited in flames and consequently can be determined at low concentrations by flame emission. The characteristic emission lines of these metals (e.g., 589.0 nm and 589.6 nm for the WebAtomic absorption spectrometry (AAS) is an easy, high-throughput, and inexpensive technology used primarily to analyze elements in solution. As such, AAS is used in food and beverage, water, clinical research, and pharmaceutical analysis. It is also used in mining operations to determine, for instance, the percentage of precious metal in ores.

WebDescribe the procedure of Flame atomization. 1. Sample is put into nebulizer which turns samples into smaller and smaller drops (Aerosol) 2. Baffles mix sample mist from oxidant and feul 3. Sample droplets enter the flame, evaporate, and decompose to atoms What is the biggest disadvantage of Flame atomization? WebAn interesting aspect of flame spectroscopy is that a flame can be too hot to yield good elemental emissions. Too hot a flame can thermally ionize many of the atoms and reduce the population of the emissive element. This propensity of luminescent species to ionize can be suppressed by increasing the concentration of free electrons in this flame.
