The Agilent 1290 Infinity LC System - Product Description
2
New Features of the Agilent 1290 Infinity LC System
•
Data collection rates up to 160 Hz with full spectral information.
•
New range of ZORBAX RRHD sub-two micron particle size columns for
operation at pressures up to 1200 bar.
•
Blend Assist for automatic buffering and additive blending in the 1290
Infinity Quaternary Pump.
The most significant advance is the range of pressures and flow rates that the
system can use. This operating envelope can be described as the power range
(flow x pressure) of the instrument and is most easily understood in graphical
form (
on page 23). As can be seen from the diagram the power range
for the 1290 Infinity pump allows 1200 bar operation up to 2 ml/min flow,
reducing to 800 bar as flow increases to 5 ml/min. This encompasses the
operating range envelopes of all pre-existing UHPLC systems on the market
and makes possible the direct transfer of methods from any of these systems
to the 1290 Infinity system.
