‘Weighing’ atoms
Mass spectrometry is an accurate instrumental technique used to determine the relative isotopic mass (mass of each individual isotope relative to carbon-12) and the relative abundance for each isotope. From this, the relative atomic mass of the element can be calculated.
Some uses of mass spectrometry include:
carbon-14 dating
detecting illegal drugs
forensic science
space exploration.
