How High Performance Liquid Chromatography Works
Basic Principle of HPLC
The principle of High Performance Liquid Chromatography is based on the interaction between two phases:
- Mobile Phase – Liquid solvent carrying the sample
- Stationary Phase – Solid material packed inside the column
Different compounds interact differently with these phases, causing separation as they travel through the column at different speeds.
Key Components of an HPLC System
1. Solvent Reservoir
Stores the mobile phase solvents used during analysis.
2. Pump
Generates high pressure to move solvents through the system at controlled flow rates.
3. Injector
Introduces the sample into the mobile phase stream.
4. Column
The most important component where actual separation occurs.
5. Detector
Detects separated compounds and converts them into electronic signals. Common detectors include:
- UV Detector
- PDA Detector
- Fluorescence Detector
- Refractive Index Detector
6. Data System
Processes detector signals and generates chromatograms for analysis.
Advanced HPLC machines from Lasany International are designed with precision-engineered components for dependable laboratory performance.
Step-by-Step Working Process of HPLC
The working process of High Performance Liquid Chromatography includes:
- Mobile phase preparation
- Solvent pumping through the system
