All pumps are equipped with an active rear-seal wash system as a standard component.
New 'system wellness' technology monitors the tightness of piston seals, the degasser vacuum, and the level of rear-seal wash solution.
System wellness reduces the risk of unexpected failure and the need for sample re-analysis.
The durability of pistons and seals is increased and the cost of operation is reduced.
Dionex SmartFlow technology provides pulse-free, precise and accurate flow and gradient delivery for any eluent combination, at any system pressure and without the need for manual adjustment of compressibility settings.
A pulse damper is not required.
Typical disadvantages of pulse dampers, including a large pressure-dependant delay volume, are eliminated.
A set of interchangeable mixer options accommodates special application needs.
It allows the gradient pumps to be optimised for the smallest delay volume (<70µl for the high-pressure gradient system) or for complete mixing of poorly miscible eluents.
A complete set of instrument qualification and documentation features for the P680 (available when operated with the Chromeleon chromatography management system) facilitates compliance with GLP, GMP and 21 CFR Part 11.
Summit HPLC systems combine the most advanced HPLC pumps and sophisticated autosamplers with a variety of high sensitivity detectors to provide uncompromised performance.
When used in combination with Chromeleon chromatography software, the most powerful and versatile data system available, the Summit HPLC system adapts to your most demanding HPLC requirements. Request a free brochure from Dionex ...
