There are several different types of mass spectrometers.
00:05
I will describe the mass spectrometer that is described in your textbook.
00:10
Not all of them operate in this fashion, but many of them operate in a similar fashion.
00:20
First we have an apparatus that is under vacuum, so there's very little air pressure inside.
00:29
We introduce our sample.
00:32
The sample then becomes radiated with electrons.
00:37
The sample comes in, it's radiated with electrons.
00:44
These electrons typically kick off electrons so that we have cat ions that then are representative of the element, or it might even be the fragment of a molecule.
01:00
There's often some lenses that these cat ions have to pass through in order to get them to the magnetic field...
