The quaternary pump comprises an optional solvent cabinet, a vacuum degasser and a four-channel gradient pump. The four-channel gradient pump comprises a high-speed proportioning valve and a pump assembly. It provides gradient generation by low pressure mixing. A solvent cabinet provides enough space for four one- liter bottles. An active seal wash (optional) is available when the quaternary pump is used with concentrated buffer solutions.
Specifications:
| Type | Specifications |
|---|---|
| Hydraulic system | Dual piston in series pump with servo-controlled variable stroke drive, power transmission by gears and ball screws, floating pistons |

| Local control | Agilent Instant Pilot |
| Analog output | For pressure monitoring, 2 mV/bar, one output |
| Communications | Controller-area network (CAN), RS-232C, APG Remote: ready, start, stop and shut-down signals, LAN optional |
| Safety and maintenance | Extensive diagnostics, error detection and display through Agilent LabAdvisor, leak detection, safe leak handling, leak output signal for shutdown of the pumping system. Low voltage in major maintenance areas. |
| GLP features | Early maintenance feedback (EMF) for continuous tracking of instrument usage in terms of seal wear and volume of pumped mobile phase with pre-defined and user settable limits and feedback messages. Electronic records of maintenance and errorsHousingAll materials are recyclable |
