C3: Instrumental Analysis Flashcards
What is chromatography?
A technique used to separate a mixture of substances using a stationary and moving phase.
What is gas-liquid chromatography?
This separates compounds that are easily vapourised
What is gel permeation chromatography?
Separating compounds according to the size of their molecules.
What is ion-exchange chromatography?
Separating compounds containing differently charged particles
What is gel electrophoresis?
Chromatography which uses an electric field to separate compounds moving across a gel covered plate.
What is high performance liquid chromatography?
Separating compounds in a solution.
What is mass spectrometry?
Provides information about elements and compounds
Tells us its relative mass
And information about its structure because some break up as they go through the spectrometer
