Study Notes

High-Performance Liquid Chromatography (HPLC)

Main purpose: Separate, identify, and quantify the components of a mixture
Mobile phase function: Carries the sample through the column, allowing the separation of components based on their interactions with the stationary phase
Stationary phase purpose: Interacts with the components of the sample, separating them based on their unique properties
Detector output: Produces a chromatogram, a graphical representation of the separated components
Peaks in the chromatogram: Represent individual components of the original mixture, with each peak corresponding to a single component
