Agilent Technologies 1260 Infinity User Manual Isocratic pump and quaternary pump. 2010 receive no greater than Restricted Rights as defined in FAR 52. Page 8: Introduction To The Pump Introduction Introduction to the Pump Introduction to the Pump Introduction to the Agilent 1260 pump service manual 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. Page 10: Overview Of The Hydraulic Path Introduction Overview of the Hydraulic Path 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. Page 12 Introduction Overview of the Hydraulic Path Figure 4 Hydraulic Path of the Quaternary Pump How Does the Pump Work?

In the quaternary pump, the liquid runs from the solvent reservoir through the degasser to the MCGV and from there to the inlet valve. For the isocratic pump, the solvent bottle is directly connected to the inlet valve. Page 13 Introduction Overview of the Hydraulic Path limit and leaves it at its top. The outer diameter of the piston is smaller than the inner diameter of the pump head chamber allowing the solvent to fill the gap inbetween. 100 µL depending on the flow rate. Page 14 Introduction Overview of the Hydraulic Path When turned on, the pump runs through an initialization procedure to determine the upper dead position of the first piston.

The first piston moves slowly upwards into the mechanical stop of the pump chamber and from there it moves back for a defined distance. Page 16 Introduction Overview of the Hydraulic Path With a compressibility value set the processor calculates a compensation volume, that depends on the back pressure of the system and the selected compressibility. This compensation volume will be added to the normal stroke volume and compensates the previously described loss of volume during the delivery stroke of the first piston. Page 17: Early Maintenance Feetback Introduction Early Maintenance Feetback Early Maintenance Feetback Maintenance requires the exchange of components which are subject to wear or stress. Ideally, the frequency at which components are exchanged should be based on the intensity of usage of the module and the analytical conditions, and not on a predefined time interval. Page 18: Instrument Layout Introduction Instrument Layout Instrument Layout The industrial design of the module incorporates several innovative features. It uses Agilent’s E-PAC concept for the packaging of electronics and mechanical assemblies.

Page 19: Electrical Connections There are no externally accessible fuses, because automatic electronic fuses are implemented in the power supply. Never use cables other than the ones supplied by Agilent Technologies to ensure proper N O T E functionality and compliance with safety or EMC regulations.
