Introduction to the Quaternary Pump
Introduction to the Quaternary Pump
The quaternary pump comprises a 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. Degassing is a must for a low-pressure
gradient system therefore the Agilent 1200 Series vacuum degasser is part of
the quaternary pump system. 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.

Introduction 1
Overview of the Hydraulic Path
Overview of the Hydraulic Path
The quaternary pump is based on a two-channel, dual plunger in-series design
which comprises all essential functions that a solvent delivery system has to
fulfill. Metering of solvent and delivery to the high-pressure side are
performed by one pump assembly which can generate pressure up to 400 bar.
Degassing of the solvents is done in a vacuum degasser and solvent
compositions are generated on the low-pressure side by a high-speed
proportioning valve.
The pump assembly includes a pump head with an active inlet valve which has
an replaceable cartridge, and an outlet valve. A damping unit is connected
between the two plunger chambers. A purge valve including a PTFE frit is
fitted at the pump outlet for convenient priming of the pump head.
An active seal wash (optional) is available when the quaternary pump is used
with concentrated buffer solutions.
