Atomic absorption spectrophotometry is a method in analytical chemistry.
Spectral interference is more common in atomic emission spectroscopy due to overlapping spectral lines.
Atomic absorption spectroscopy typically has a lower detection limit compared to atomic emission spectroscopy because it measures the amount of light absorbed by atoms in a sample, which is more sensitive at low concentrations. Atomic emission spectroscopy, on the other hand, measures the intensity of light emitted by atoms, which can be affected by background noise and matrix effects, leading to a higher detection limit.
There are lots of ways. Atomic absorption spectroscopy comes to mind.
Both flame emission and atomic absorption spectroscopy are analytical techniques used to determine the concentration of elements in a sample. The main similarity is that they both rely on the excitation of atoms in the sample to emit or absorb specific wavelengths of light. The main difference is that in flame emission spectroscopy, the intensity of emitted light is measured, while in atomic absorption spectroscopy, the amount of light absorbed by the atoms is measured.
Source modulation in atomic absorption spectroscopy is used to enhance sensitivity and reduce background noise. By modulating the lamp intensity at a specific frequency, it becomes easier to distinguish the absorption signal from the baseline noise, leading to better detection limits and accuracy in the analysis.

Fluorescence spectroscopy is a type of spectroscopy that analyzes fluorescence from a provided sample. This uses a beam of light, often an ultraviolet light which then causes absorption spectroscopy to occur.

Atomic absorption spectroscopy works by passing a light beam through a sample containing the element of interest. The atoms in the sample absorb specific wavelengths of light, which are then measured to determine the concentration of the element in the sample.
