What kinds of particles do we use in mass spectrometry? is it anions, cat ions, radicals, or all of the above? so mass spectrometry, you want to divide things based on their mass.
00:15
And to start with, you make sure they are ionized, and you want them all to have the same charge, either possible negative, rather than the exact same charge, but the same polarity.
00:27
And then you accelerate them, and then you deflect them with magnetic.
00:30
Field and they are separated by size.
00:33
So the first goal is to produce ions.
00:38
So producing ions.
00:41
What kind of ions? well you want them all to be the same and in practice they all end up being positive.
00:51
So they're all going to be cat ions...
