1Introduction

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

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.
