High-Performance Liquid Chromatography (HPLC LI-6300)


Lasany High-Performance Liquid Chromatography system, is a sophisticated analytical instrument widely used in scientific laboratories, research institutions, and various industries. It is employed for the separation, identification, and quantification of components in complex mixtures.

High-Performance Liquid Chromatography (HPLC) is a powerful analytical technique used to separate, identify, and quantify components in a mixture. The HPLC LI-6300 is a specific model that incorporates advanced features for efficient and precise chromatography.



High-Performance Liquid Chromatography (HPLC)

HPLC is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. Each component in the sample interacts slightly differently with the adsorbent material, causing different flow rates for the different components and leading to their separation as they flow out of the column.

Key Components

  1. Solvent Reservoirs: Hold the mobile phase solvents.
  2. Pump: Delivers the mobile phase at a high pressure to the system.
  3. Injector: Introduces the sample into the mobile phase stream.
  4. Column: Packed with stationary phase material where separation occurs.
  5. Detector: Identifies and quantifies the components as they elute from the column.
  6. Data System: Collects and analyzes the data.

Working Principle

  1. Injection: The sample mixture is injected into the mobile phase stream.
  2. Separation: As the sample flows through the column, components interact with the stationary phase and are separated based on their differing affinities.
  3. Detection: Separated components are detected, and a chromatogram is generated.

HPLC LI-6300 Model

The LI-6300 is an advanced HPLC system designed for high precision and efficiency. Here are some of its key features:


  1. High-Pressure Capability: The LI-6300 can operate at high pressures, allowing for the use of smaller particle size columns for better separation.
  2. Precise Flow Control: Advanced pump systems ensure consistent and accurate flow rates.
  3. Automated Sample Injection: The system can be equipped with an auto-sampler for high-throughput analysis.
  4. Multiple Detectors: Compatible with various detectors (e.g., UV, PDA, fluorescence) for diverse analytical needs.
  5. Temperature Control: Column ovens and thermostats maintain optimal conditions for reproducible results.
  6. Data Management: Integrated software for data acquisition, processing, and reporting.


The HPLC LI-6300 is used in various fields, including:

  • Pharmaceuticals: Quality control, drug development, and stability testing.
  • Food and Beverage: Analysis of additives, contaminants, and nutritional content.
  • Environmental Testing: Detection of pollutants and contaminants in water, soil, and air.
  • Chemical Research: Separation and analysis of complex mixtures.


  • High Resolution: Superior separation of complex mixtures.
  • Speed: Rapid analysis compared to traditional column chromatography.
  • Sensitivity: Capable of detecting low concentrations of analytes.
  • Reproducibility: High precision in repeated analyses.
