Product Description
Product Description
The new Agilent 1260 Infinity II Flexible Pump improves your everyday
efficiency by combining the performance of a high-pressure mixing UHPLC
pump with the flexibility of a low-pressure mixing UHPLC pump.
The power range of 5 mL/min with a maximum pressure up to 800 bar allows
to run HPLC and UHPLC methods on the same LC system. Intelligent System
Emulation Technology enables the transfer from existing methods from
different LC systems - current Agilent systems as well as instruments from
other manufacturers.
The Agilent Inlet Weaver mixer, active damping, or the optional Agilent Jet
Weaver mixers for additional mixing capacity achieve high analytical
efficiency.
The established multipurpose valve enhances laboratory efficiency by adding
useful functionalities, for example, mixer in/out switch, filter backflush, or
automatic purge.
BlendAssist software simplifies your workflow with accurate buffer/additive
blending.

Introduction

Operating Principle
Operating Principle
The pump head comprises two pump chambers in series with independent
high-resolution motion control. A pressure sensor in the flow path monitors
the pressure. The pump control uses this signal for minimizing the pressure
ripple in order to achieve highest flow precision. A stable flow can be
delivered even in case of eventual small internal leaks, which can be
compensated automatically. A heat exchanger between two pump chambers
strongly reduces thermal effects due to solvent compression under very high
pressures.
As solvents are compressed by the pump head and expand further down the
flow path, for example in the column, the volumetric flow is changed
depending on the compressibility of the liquid. Agilent control software allows
specifying pure solvents, pre-mixed solvents and solvent gradients. Associated
Agilent solvent libraries are used by the pump control for enhanced flow
accuracy, which is required for cross-instrument or cross-system
reproducibility and method compatibility.
A high resolution encoder unit is attached to the pump drives, which divides a
single turn into 65000 steps. Each step corresponds to a volume of about
300 pL, which allows an extremely precise control.

Positions of the Multi Purpose Valve
The Multi Purpose Valve allows easy software controlled switching between
different modes of operation.
Normal Operating Mode Without Mixer
In normal operating mode, the flow comes from the pump head, passes the
pressure sensor and arrives at the central port of the Multi Purpose Valve. The
flow leaves the valve through port 4 to the system (autosampler etc.).

Leak and Waste Handling
Leak and Waste Handling
The Agilent InfinityLab LC Series has been designed for safe leak and waste
handling. It is important that all security concepts are understood and
instructions are carefully followed.
The solvent cabinet is designed to store a maximum volume of 8 L solvent. The
maximum volume for an individual bottle stored in the solvent cabinet should
not exceed 2 L. For details, see the usage guideline for the Agilent Infinity II
Solvent Cabinets (a printed copy of the guideline has been shipped with the
solvent cabinet, electronic copies are available on the Internet).
All leak plane outlets are situated in a consistent position so that all Infinity
and Infinity II modules can be stacked on top of each other. Waste tubes are
guided through a channel on the right hand side of the instrument, keeping the
front access clear from tubes.
The leak plane provides leak management by catching all internal liquid leaks,
guiding them to the leak sensor for leak detection, and passing them on to the
next module below, if the leak sensor fails. The leak sensor in the leak plane
stops the running system as soon as the leak detection level is reached.
Solvent and condensate is guided through the waste channel into the waste
container:
•from the detector's flow cell outlet
•from the Multisampler needle wash port
•from the Sample Cooler (condensate)
•from the Seal Wash Sensor (if applicable)
•from the pump's Purge Valve or Multipurpose Valve
