High-Performance Liquid Chromatography (HPLC)
High-Performance Liquid Chromatography (HPLC) is an advanced analytical technique used to separate, identify, and quantify components in liquid mixtures. Unlike traditional column chromatography, HPLC uses high-pressure pumps to force solvents (mobile phase) through a column packed with fine particles (stationary phase), achieving faster and more efficient separations.
Key Details:
Category: Analytical Chemistry / Separation Technique
Chemical Formula: N/A (Technique / Method)
Components Used: Various chemical solvents and materials, such as:
Water, Acetonitrile (CH₃CN), Methanol (CH₃OH), buffer solutions, and
silica-based stationary phases (e.g., C18 bonded silica).
Description:
- High-pressure pumps force the mobile phase through a column packed with small particles for efficient separation of compounds.
- Separation occurs based on differential affinities of compounds for stationary vs. mobile phases.
- Common detectors include UV-Vis spectrophotometers or Mass Spectrometry systems for identification and quantification.
Common Uses / Applications:
- Pharmaceuticals: Drug development, impurity profiling, and stability testing of Active Pharmaceutical Ingredients (APIs).
- Biotechnology: Purification and characterization of proteins, peptides, and nucleic acids.
- Environmental Analysis: Detection of trace pollutants, pesticides, and toxins in water, soil, and air.
- Food and Beverage: Analysis of vitamins, additives, preservatives, and contaminants.
- Forensic Science: Identification of illicit drugs and toxic substances.
Key Features:
- High separation efficiency and speed compared to traditional chromatography.
- Versatile for a wide range of chemical and biological samples.
- Compatible with multiple detectors for qualitative and quantitative analysis.
