Question

How does a magnet separate fragments ? (In mass spectrometry)

Please don't copy and paste the same old question's answer. That one is incorrect.

Answer 1

Answer – We know when we inject the compound in the mass spectroscopy there is first sample gets ionized with the help of bombarded electrons from the hot filament and form the cations, this cation is pushed due to the plate charged positive or repellor electrode. When this cations and neutral fragments come in the perpendicular magnetic field then due magnetic field there is charged ions gets deflecting with respect to its mass means smaller ions defected more and higher mass ion deflected less. These ions are separated by their momentum, so the high momentum   ions goes directly without any deflecting and stick on the detector and the less momentum deflected and hit on the curved tubes. So magnet help to separate the charged ions fragments according to their masses and velocity.
