Dionex - Dionex HPLC System

Applications & Use Cases

• Separation and quantification of compounds in pharmaceutical research and quality control.
• Analysis of food and beverage components for quality assurance and authenticity.
• Environmental monitoring for pollutants in water, soil, and air samples.
• Forensic toxicology for drug screening and identification.
• Biochemical research for protein and nucleic acid analysis.

Typical Specifications

Typical flow rates

Commonly ranges from 0.1 to 10 mL/min, depending on the pump configuration (analytical or semi-preparative).

Pressure range

Typically operates up to 400 bar (40 MPa) for standard HPLC, with some systems reaching higher pressures.

Detector types

This system includes Absorbance (UV-Vis) and Electrochemical detectors. Other common types for this class of equipment include Refractive Index (RI) and Fluorescence.

Autosampler capacity

For this class of equipment, autosamplers typically hold between 50 and 100 vials, though larger capacities are available.

Power supply

Units of this type commonly require a standard single-phase electrical supply, typically 230V, 50Hz for the UK market.

Temperature control

The chromatograph oven typically offers temperature control from ambient +5°C to 80°C for column stability.
