1) Capillary Electrophoresis
only tricky question when talking about the setup after naming everything: what else do you need? answer: more positive charged molecules than negative (depending on the electrodes) so that the electroosmotic flow can be generated in the intended direction.

2)ESI
Electrospray ionization, quite detailed.
tricky question: what are the two methods to form the droplets? answer: dispersion by electro spray into a fine aerosol or via an extra electric field applied between the tip of the needle and the space after.

Duration: 20 min

More detailed examiner than anticipated.
