When white light from Mercury vapour lamp is passed through sodium vapour then we have as outcome a continuous spectrum of colours with two black lines in the yellow-orange region. These two lines stand for the absorption of 5890 A and 5896 A lines of sodium atom

Another example is Fraunhofer lines seen in the continuous spectrum got from sun. These lines are due to absorption of characteristic frequencies of metals present in the chromosphere of the sun

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.


Is spectral interference more common in atomic emission spectroscopy or atomic absorption spectroscopy?

Spectral interference is more common in atomic emission spectroscopy due to overlapping spectral lines.


Why does atomic absorption spectroscopy often have a low detection limit that atomic emission spectroscopy?

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.


How do you test iron ions?

There are lots of ways. Atomic absorption spectroscopy comes to mind.


What is the simailarity and difference of flame emission and atomic absorption spectroscopy?

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.

How does atomic absorption spectroscopy work to analyze the concentration of elements in a sample?

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.


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.
