When is atomic absorption more sensitive than atomic emission in atomic absorption spectrometers?
Atomic absorption is more sensitive to atomic emission when the excitation potential is greater than 3.5eV.
What are the strenghts of atomic absorption spectrometry compared to atomic emission spectrometry?
Atomic absorption spectrometry is more sensitive than atomic emission spectrometry.
What are the application of atomic absorption spectrometry in pharmaceutics?
Atomic absorption spectrometry is used for the determination of metal residues remaining from pharmaceutical manufacturing.
Who uses atomic absorption spectroscopy?
Atomic absorption spectroscopy is used by chemists, environmental scientists, and researchers to detect and quantify the concentration of metallic elements in a sample. Industries such as pharmaceuticals, agriculture, and metallurgy also rely on atomic absorption spectroscopy for quality control and regulatory compliance.

What is the use of Atomic Absorption in Forensic?
Atomic absorption is used in forensics to analyze trace elements in samples such as blood, hair, or soil. By measuring the absorption of specific wavelengths of light by the atoms in the sample, atomic absorption spectroscopy can determine the presence and concentration of elements like arsenic, lead, or mercury, which can be crucial in solving criminal cases.
What are the limitations of atomic absorption spectrometry?
Atomic absorption spectrometry can only be used for metallic elements. Each element needs a different hollow cathode lamp for its determination.
How atomic absorption and atomic emission are similar?
Atomic absorption and atomic emission are both analytical techniques used to identify and quantify elements in a sample based on their atomic properties. Both methods rely on the characteristic absorption or emission of light at specific wavelengths by the sample's atoms when they undergo electronic transitions. Additionally, they can both provide information about the concentration and presence of different elements in a sample.
Which gun shot residue metal will be detected by atomic absorption but not neutron activation?
Lead is a metal in gunshot residue that can be detected by atomic absorption but not neutron activation. This is because atomic absorption spectroscopy relies on the absorption of light by ground-state atoms, which lead exhibits. Neutron activation analysis, on the other hand, requires the irradiation of samples with neutrons to induce radioactivity, which is not applicable to lead.
Why is source modulation used in atomic absorption spectroscopy?
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.
Why are atomic absorption lines very narrow?
Atomic absorption lines are very narrow because they result from the absorption of light by individual atoms at specific energy levels. This absorption occurs at precise wavelengths corresponding to the energy differences between the atom's electron orbits. The narrowness of the lines is due to the limited number of possible energy transitions within an atom, resulting in distinct and well-defined absorption peaks.
