Flame in atomic absorption spectroscopy
WebGFAAs are more sensitive than flame atomic absorption spectrometers, and have a smaller dynamic range. This makes it necessary to dilute aqueous samples into the dynamic range of the specific analyte. GFAAS with automatic software can also pre-dilute samples before analysis. 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?

WebMar 16, 2024 · It is also possible to have chemical processes that interfere with atomic absorption and emission measurements. It is important to realize that the chemical interferences described herein can potentially occur in flame, furnace and plasma devices. One example of a chemical interference occurs for metal complexes that have low volatility. 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
