High performance liquid chromatography

High performance liquid chromatography

HPLC is an analytical technique used to separate, identify, and quantify components in a mixture. It operates based on the basic principle of column chromatography and utilizes spectroscopy for identification and quantification. Here are the key points:

  1. Principle:

    • HPLC separates components by passing the mixture through a high-pressure column filled with porous particles.
    • The mobile phase (solvent or solvent mixture) is forced through the column.
    • Components interact differently with the stationary phase, leading to varying migration rates.
    • After leaving the column, individual substances are detected by a suitable detector.
    • The resulting chromatogram allows identification and quantification.
  2. Instrumentation:

    • Pump: Generates a consistent flow of eluent into the system under high pressure.
    • Injector: Introduces the sample into the eluent flow (often using sampling loops or autosamplers).
    • Detector: Identifies and quantifies separated components.
    • Computer: Analyzes data and displays the results.
