The principle is that each element has a specific wavelength for absorption. As in the molecular spectrophotometry the Lambert-Beer equation is used. The samples to be analyzed are atomized by different techniques (flame, graphite tube). The method is very useful because is accurate and specific. We need of course a series of standard solutions for each element.

How do you find copper in brass using the spectrophotometer absorptions?
Digest (dissolve) a small portion of the brass in nitric acid. Then test the sample for copper content using an atomic emission or atomic absorption spectrometer.
What is the Detection limit of atomic absorption spectroscopy?
ability of instrument to determine its desired elements
Advantages of atomic absorption spectroscopy?
Because it is Gosh get with the programme guys
What instrument measures atomic mass?
A very accurate mass spectrometer is needed.
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 is the device used to determine atomic masses?
spectrometer
What is analytical istrument?
An analytical instrument is the instrument used to determine the chemical composition of materials, qualitatively or quantitatively; ex.: internally coupled plasma mass spectrometer, polarograph, atomic absorption spectrometer, X-ray spectrometer, coulometer, Karl Fischer titrator, etc.

How do you determine the mass of atom using mass spectrometer?
Actually in mass spectrometer the isotopes of an element are separated by applying magnetic field.Each isotope is then compared with carbon-12 to get the atomic mass of that isotope.

How is cleavage related to atomic structure?
Cleavage is related to the minerals atomic structure because minerals are arranged in crystal lattices . It's the shape of these lattices that determine the mineral's cleavage.

Who uses atomic absorption spectroscopy?
Atomic absorption spectrophotometry is a method in analytical chemistry.
What are the strenghts of atomic absorption spectrometry compared to atomic emission spectrometry?
Atomic absorption spectrometry is more sensitive than atomic emission spectrometry.
