WebTo get the abundance of each isotope, you could use a tool called a mass spectrometer. Basically how it works is that you have a stream of ionized atoms of one element. Then, you use a magnet to try and kick them out of their path. The ones that are the heaviest will be pushed less, and the lighter ones will be pushed more.
