Retains the excellent basic functions developed in the LC-20AD, with modifications of the pressure sensor, drain valve, and plunger seal added to expand the maximum allowed pressure to 66 MPa for extra-resolution applications under such high pressure.
Superior Solvent Delivery Performance
The LC-20ADXR offers the fastest solvent delivery performance in the world. With an automatic pulsation-correction mechanism and high-speed micro plunger driving, it achieves pulse-free solvent delivery. Thanks to improvements in solvent-delivery control firmware, solvent-delivery performance in the micro-flow-rate range below 50 μL/min has been significantly improved.
Low-Pressure Gradient Unit
The optional low-pressure gradient unit can be incorporated in the LC-20ADXR, enabling gradient elution in a compact space with a small void volume. Automatic matching adjustment of the solenoid valve and pump gives concentration accuracies of ±1.0%
A new type of plunger made with a technique that reflects consideration of the material structure and a precise plunger-holding mechanism help to increase the service life of plunger seals and enable stable solvent delivery over long periods.
Pressure Tolerance:
- Up to 66 MPa (approximately 660 bar) for flow rates from 0.0001 to 3 mL/min.
- Up to 44 MPa (approximately 440 bar) for flow rates from 3.0001 to 5 mL/min.
Flow Rate Range:
- 0.0001 to 5 mL/min.
