Quaternary Hplc Pumps

UltiMate™ LPG-3400RS Rapid Separation Quaternary Pump Thermo Scientific™

For the highest degree of flexibility with solvent proportioning in UHPLC or conventional LC, the Thermo Scientific™ Dionex™ UltiMate™ LPG-3400RS Rapid Separation Quaternary Pump supports ternary and quaternary gradients over an industry-leading flow-pressure footprint. It supports the use of up to four solvents at up to 15,000 psi (100 MPa) and a recommended flow rate range from 200µL to 8.0mL/min. with excellent flow stability. This pump adapts easily to multiple fast routine applications or method development in the pharmaceutical, food and beverage and environmental industries.

Vanquish™ Quaternary Pumps Thermo Scientific™

Extend the capabilities of the Thermo Scientific™ Vanquish™ LC platform by adding the flexibility of state-of-the-art quaternary solvent blending. Thermo Scientific™ Vanquish™ quaternary pumps incorporate SmartFlow™ pumping technology to ensure excellent flow and gradient precision, independent of eluent composition, at backpressures up to 1034 bar. These innovations give you unrivaled retention time precision and the highest confidence in your data, even when running ternary and quaternary gradients. They also provide more freedom for method transfer, method development, and application switching.

UltiMate™ LPG-3400XRS Extended Pressure Range Quaternary Pump Thermo Scientific™

Enjoy the flexibility of a quaternary pump with the fast gradient performance of a binary pump. The unique Thermo Scientific™ Dionex™ UltiMate™ LPG-3400XRS Extended Pressure Range Quaternary Pump is an LC/MS optimized quaternary UHPLC pump offering state-of-the-art performance for high speed and ultrahigh resolution applications. The compact pump head design, with a gradient delay volume of just 200µL, supports ballistic gradients for ultrahigh throughput. A combination of speed and flexibility in solvent proportioning makes this pump the first choice as an LC front-end for MS and MS/MS.

UltiMate™ LPG-3400SD Standard Quaternary Pump Thermo Scientific™

For flexibility across a broad range of analytical LC applications with the highest degree of choice in solvent proportioning and mixing, the Thermo Scientific™ Dionex™ UltiMate™ LPG-3400SD Standard Quaternary Pump is the pump of choice. Up to four solvents may be used for convenient method development, system flushing or solvent preparation. With support for pressures up to 62 MPa (9,000 psi/620 bar) at flow rates of up to 10mL/min., the UltiMate 3000 SD pumps excel in standard LC applications while offering full compatibility with fast UHPLC separations.
