Atomic Spectroscopy for Elemental Analysis

Atomic Spectroscopy

• The primary focus of Atomic Spectroscopy is to identify and quantify the elemental composition of a sample.

Flame Atomic Absorption Spectroscopy (FAAS)

• The technique used in FAAS to break molecules into gaseous atoms is thermal decomposition.
• The monochromator acts as the wavelength selector, separating the light into its component wavelengths.
• Concentrations are typically measured at the low mg/L (ppm) level in FAAS.
• The type of atoms that absorb light from the source in FAAS are ground-state atoms.
• The primary purpose of FAAS is to quantify the concentration of a specific element in a sample.
• The function of the monochromator in FAAS is to select the specific wavelength of light that corresponds to the energy transition of the analyte element.
• The source of radiation in FAAS is a hollow cathode lamp, which emits light at a specific wavelength.
• The principle work of FAAS is to measure the absorption of light by ground-state atoms in a sample.
• The component responsible for measuring concentrations at the low mg/L (ppm) level in FAAS is the detector.
