PHYSICS 3B Chapter Notes - Chapter 29: Mass Spectrometry
Document Summary
Aurora borealis 1 australis northern s southern lights ) are caused by charged partners from the saar wind forced to spiral along earth "s magnetic field vines. They collide with air molecules and ionize the air as they spiral downward near the nl 5 poles mass spectrometer a- Lorentz ean : e" determine an unknown sample"s chemical. Device that uses the criminal path of charged particles in a b field to measure the masses of atoms and composition. Usually has 2 sections of magneto fields - b" " if a charged particle is moving in both b" and i" If a charged particle is moving through perpendicular i" particular speed v - This is how you filter particles by their velocity - only allow those m constant v into second part. " all the atoms reaching the second magnetic field b" will have the same speed v -
