L1 Mass Spectrometers

Mass Spectrometers 1
A. The charge to mass ratio of the fragment ions

Mass Spectrometers 2
A. Ions
B. A stream of electrons are directed at a vaporised sample, to eject other electrons from the molecules of the sample, producing positive ions.

Mass Spectrometers 3
A. Electric, parallel
B. The heavier particle will have a smaller acceleration over the same distance and therefore a lower final speed.

Mass Spectrometers 4
A. Velocity selector; only the particles with a particular velocity can pass through.

Mass Spectrometers 5
A. Magnetic, perpendicular.
B. Circular path
C. A heavier particle will travel at the same speed and follow a curved path with a greater radius.

Mass Spectrometers 6
A. pulsed laser, attracted, accelerated.

Mass Spectrometers 7
A. It can be done with short lived molecules such as reactive intermediates in chemical reactions.

Mass Spectrometers 8
A. 2, 4, 7
