Typical flow rate range

Typically 0.01 to 10 mL/min, suitable for analytical and semi-preparative applications.

Detector type

This unit features UV/Vis detection, commonly found on units of this type, offering reliable absorbance measurement.

Pump type

Typically a quaternary solvent management system, allowing for flexible gradient elution.

Maximum operating pressure

For this class of equipment, pressures up to 5000 psi (345 bar) are common.

Power supply

Commonly operates on standard laboratory power, typically 230V, 50Hz in the UK, with specific power draw varying by configuration.

Footprint

A modular system, typically requiring a bench space of approximately 60-80 cm wide and 60-70 cm deep for the main components.

• What is High-Performance Liquid Chromatography (HPLC)?

  HPLC is an analytical chemistry technique used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurised liquid solvent containing the sample mixture through a column filled with a solid adsorbent material.

• What maintenance is typically required for an HPLC system?

• Can this system be used for different types of samples?

• What are the benefits of UV/Vis detection in HPLC?

• Is training required to operate an HPLC system?

Chromatography systems command strong respect within analytical and pharmaceutical sectors. Buyers typically prioritise equipment with verified maintenance records and clear calibration history, as these directly affect analytical accuracy. Used units from established manufacturers remain highly valued for their reliability. Key strengths include reproducible results, robust construction, and established spare parts availability. Industry sentiment reflects confidence in these systems when sourced from reputable suppliers with transparent service documentation.
