This is simple explanation of the question.
Yes, the data from mass spectrometry has helped modern scientists to make modifications to Dalton's model.
Dalton's model consisted of a single atom and that basically the atom is the smallest object. At the time, no discovered what are inside of atoms.
Atoms are made up of small particles, protons, neutrons and electrons. A mass spectrometer is an instrument that is able to see what is inside an atom. With this item, scientists have proved that atoms are not the smallest in the world cause the objects in them are smaller.
