Graphite Furnace
A typical electrothermal atomizer, also known as a graphite furnace, consists of a cylindrical graphite tube approximately 1–3 cm in length and 3–8 mm in diameter. As shown here, the graphite tube […]
Cross-Sectional Profile of Flame in FAAS
The illustration below shows a cross-section through a typical flame looking down the burner’s slot along the source radiation’s optical path. The primary combustion zone is usually rich in gas combustion products that […]
Absorbance vs. Height Profiles in FAAS
Where within the flame one measures absorbance is critical as two competing processes affect the concentration of free atoms in the flame. The more time the analyte spends in the flame the […]
Atomizer for Flame Atomic Absorption Spectroscopy
The photos below shows a typical assembly for flame atomization with close-up views of several key components. In the unit shown here, the sample is drawn into the assembly by passing a […]
