600E Waters Multisolvent Delivery System

The Waters 600E system is a high-performance liquid chromatography (HPLC) multisolvent delivery system with a 225 µL pump head volume at 45 mL/min flow rate or 100 µL pump head volume at 20 mL/min flow rate. It has a 0.01 to 45.0 mL/min operating flow rate range adjustable in 0.01 mL/min increments. It also has a single keypad control with PowerLine™ system controller. Its method storage allows access to previously created gradient, event, autosampler, and detector programs. It has eleven preprogrammed gradient profiles including: Step change at start of segment, Step change at end of segment, Linear change, Four convex gradient curves, and Four concave gradient curves. System control of PowerLine detectors and autoinjectors through IEEE-488 interface. RS-232 serial communications interface. Polymeric and stainless steel flow path with low-permeability CO2/O2 tubing.

Waters 600 Controller:
Controls eluent gradient, flow rate, external events, and sparging for the Waters 600E system. Provides connection terminals and communication ports for operation with and control of external devices, such as detectors, autosamplers, and data systems.

Waters 600E Pump:
Contains components required to blend and to deliver eluents from the eluent reservoir bottles to the injector and column. Consists of the pump with 225 µL or 100 µL volume pump heads, eluent sparge valve assembly, eluent proportioning valve assembly, manual injector, and vent valve.

Rheodyne 7725i Manual Injector Load/Inject Handle
Connects and disconnects the sample loading loop from the system. Allows variable-volume injections from a fraction of a µL to 20 µL without changing loops.

----------
The Waters 600S Controller features a 5-inch, 320 x 200 LCD, program tables with 15 time-based steps per table, and a 15 table capacity. The 600S provides single-keyboard control of Waters autosamplers, and uses the Waters AutoBlend method for automatic buffer blending. The unit features a random phase synchronization algorithm, a proportioning valve which automatically adjusts to the eluent composition percentage.
