Best Answer

The electromagnetic field used in a mass spectrometer is used to guide the sample ions in the right direction, towards the detector. It interacts with charged particles (ions), and depending on their weight and charge, they curve a different amount, landing on different parts of the detector, and thus allowing their molecular weight to be determined.

Why do atoms need to be ionised in a mass spectrometer?

it is necessary to ionize the compouned or element used in the expirement because ONLY electrically charged particles (IONS) are affected by the magnetic field . (i.e : only ions are deflected by the magnetic field )Hope that this was helpful !!

Is massive an adjective?

Yes, it is an adjective, but has come to mean "having a large mass", e.g. huge.The noun mass is more often used as an adjunct when describing just mass (mass spectrometer, mass increase) or as an adjective meaning something affecting masses of people (mass hypnosis, Mass Communication).
