E.g. HPLC instruments consist of a solvent pump(s), solvent reservoirs, separation column, and detector. HPLCs usually use a UV spectroscopy based (or PDA) detector, but can be in-line with other instruments such as a mass spectrometer. E.g.
The basic methods of separation in HPLC rely on a mobile phase (water, organic solvents, etc.) being passed through a stationary phase (particulate silica packings, monoliths, etc.) in a closed environment (column); the differences in reactivity among the solvent of interest and the mobile and stationary phases distinguish compounds from one ...
