Liquid chromatography. Researcher extracting a liquid sample from a vial. The liquid will be placed in the machine in the background to analyse it and discover the exact composition of the sample. The machine uses the technique of liquid chromatography to separate components of a mixture. Specifically, it is a fast protein liquid chromatography (FPLC) system, using column chromatography to separate or purify proteins from complex mixtures. Photographed in a laboratory in Edinburgh, Scotland, as part of research into brain synapses.
