LC-500A (Dual Pump) Liquid Chromatograph

Performance Features:

The LC-500 High-Efficiency HPLC features a static motor control circuit designed with proprietary technology, which implements automatic feedback tracking of motor control signals, effectively enhancing motor control accuracy, and ensuring the reliability and stability of the pump.

Pump configuration: Series or parallel dual plunger

Floating self-correcting seal technology and pump head self-cleaning function technology, which extend the service life of seals and ensure the durability and high efficiency of instruments.

User-friendly flow and pressure calibration features ensure high accuracy and stability of the instrument.

We utilize two gradient-based program designs: linear and step gradients are available options.

Programmatic solvents and compression factors, capable of automatic compensation

Complete pre-washing function, with quick solvent change capability

Utilize holographic dual-grating technology

Utilizes high-precision photodiode design to expand the linear range

Convenient, quick, and unique automatic self-correction feature for intensity gain coefficient

Terbium glass pool design, full-wavelength scanning, convenient for accurate wavelength calibration

Universal sample pool design, easy to switch between微量 and constant pools

Deuterium lamps are easy and quick to replace, ready for use without the need for calibration.
