Introduction to the 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. 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 to the Pump

Introduction to the Isocratic Pump

The isocratic pump has the same operating principle as the quaternary pump

but has only one solvent channel, that means the composition cannot be

changed during a method because there is no multi-channel gradient valve

(MCGV). The isocratic pump does not include a degasser. An upgrade product

(Isocratic to Quaternary Pump Upgrade Kit (p/n G4207-60000)) is available

for upgrading the isocratic pump to a quaternary pump including a degasser.

1Introduction

Overview of the Hydraulic Path

Both the isocratic pump and quaternary pump are 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 600 bar.

In the quaternary pump, degassing of the solvents is done in a built-in vacuum

degasser. Solvent compositions are generated on the low-pressure side by a

high-speed proportioning valve (MCGV).

The pump assembly includes a pump head with a passive inlet valve and an

outlet valve. A damping unit is connected between the two piston 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 for applications using concentrated

buffers as solvents.
