🔍 Principles of HPLC: Separation and Detection
The principles of HPLC involve the separation of components in a mixture based on their interactions with the stationary phase and the mobile phase. The stationary phase is typically a solid or liquid supported on a solid, while the mobile phase is a liquid that flows through the column. As discussed in Chromatography Principles, the separation of components in HPLC is based on the distribution of the components between the stationary phase and the mobile phase. The detectors used in HPLC, such as UV-Vis Spectroscopy and Mass Spectrometry, allow for the detection and quantification of the separated components.
