Category: Techniques & Equipment
High Performance Liquid Chromatography (HPLC) is a sophisticated analytical technique that leverages high-pressure liquid chromatography to expertly separate, identify, and quantify the constituent parts of a complex mixture dissolved in a solvent. This highly effective method is utilized across various disciplines, including chemical research, bioanalytical studies, and environmental monitoring.
HPLC operates on the principle of differential partitioning between a mobile phase (liquid solvent) and a stationary phase (solid particles packed in a column):
- Sample Injection: A small volume of the sample is introduced into the mobile phase.
- Separation: As the sample travels through the column, its components interact differently with the stationary phase, causing them to separate based on their chemical properties.
- Detection: A detector (UV, fluorescence, or mass spectrometry) identifies and quantifies each component as it exits the column.
