About Instrument and its applications-
It is used to determine the concentration of metal elements in a sample. The technique makes use of the fact that neutral or ground state atoms of an element can absorb electromagnetic radiation over a series of very narrow, sharply defined wavelengths. The sample in solution is aspirated as a fine mist into a flame where it is converted into atomic vapor. Most of the atoms remain in the ground state and are therefore capable of absorbing radiation of a suitable wavelength. This discrete radiation is supplied by a hollow cathode lamp, which a sharp line source consisting of a cathode is containing the element to be determined along with the tungsten anode. The line characteristic of the element is emitted by the hollow cathode and passes through the flame where they may be absorbed by the atomic vapor, since only the test element can absorb this radiation, the method becomes specific.

The application areas of MPAES are very wide including environmental analysis, medicines, metal alloys etc.
