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.
