Answer
Aston invented the mass spectrograph, a device used to measure the masses of atoms and molecules. The mass spectrograph works by ionizing the atoms or molecules to be measured and then accelerating them through an electric field. The atoms or molecules are then deflected by a magnetic field, and the amount of deflection is related to the mass of the atom or molecule.
