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.
spectrometer
A mass spectrometer measures atomic mass by removing one or more electrons from an atom. The spectrometer then sends the atom through a magnetic field. Because of the missing electrons, the atom has more protons than electrons, resulting in a positive charge. The magnetic field bends the path of the positively charged atom as it moves through the field. The amount of bending depends on the atom's mass. The atomic mass of the atom can be calculated from the magnitude of the bend.
Using mass spectrometer, one can identify and/or separate the isotopes of the elements and also predict its composition in a given mixture.
NEUTRONS AND PROTONS are counted in an atom to determine it's mass number.
Proton + Nuetron = Atomic Mass
A very accurate mass spectrometer is needed.
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
Isotopes (of the same element) have different mass, this is measured by the mass spectrometer
Mass spectrometer would work.
mass number= no. of protons + no. of neutron
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.
