We get isotopes from the source as ions. Those ions are accelerated and then they enter the velocity selector. When the ions are accelerated, heavier ions will have a lesser final velocity compared to lighter ions. Then when they enter the velocity selector, depending on E and B, only one out of those two heavier or lighter will pass through, and get deflected in the magnetic field at the end. How are we getting two different masses out of the velocity selector? Is it that first, we get all the lighter ions detected, then we manipulate E and B of the velocity selector to get the heavier ions?

The magnetic force and the electric force on the particles are not affected by the mass. Therefore all masses come through and are then separated in the second magnetic field.
