The Agilent 1100 Series isocratic pump

The isocratic pump is a work-horse designed to meet the needs of QA/QC applications:

•            Long Instrument uptimes that reduce operating and maintenance costs.

•            A wide flow range of up to 10 ml/min for broad HPLC work, including semipreparative separations.

Built-in early maintenance feedback—EMF, built-in seif-test routines and task-oriented online help are valuable features for QA/QC Operation.

•            Upgradeable to quaternary pump

One pump head containing dual pistons in-series and the active inlet valve for excellent baseline stability and reproducibility of retention times and peak areas

The isocratic pump delivers stable retention times, run after run, day after day.

Column:           125 x 4.0 mm ODS

Mobile phase: Water/acetonitrile 85:15

Flow rate:         1.5 ml/min

Built-in leak test with graphical presentation of pressure profile ensures reliable Operation

Full programming capabilityfor the isocratic pump

Intelligent method sequencing includes built-in shutdown methods to help reduce solvent costs and prolong column lifetime by flushing after a series of runs
