1290 Infinity Flexible Cube
The Agilent 1290 Infinity Flexible Cube is an auxiliary module for the 1290 Infinity Autosampler with a built-in pump to facilitate enhanced flushing capabilities and to reduce carry-over. With access to three solvents, critical sections of flow path can be flushed at high flow rates. Automated back-flushing of the injection needle-seat achieves the absolute lowest sample carryover for LC and LC/MS applications. In addition, the Flexible Cube hosts up to two Agilent Quick-Change valves. For utmost flexibility, choose among Agilent’s broad portfolio of available valve heads suitable up to 1200 bar. The valves can be controlled independently for any demanding valve-switching application.
-
Lowest instrument-related carryover in UV and MS analyses with typically less than 10 ppm (0.001 %).
-
Guaranteed long-term low carryover for a variety of solvents and applications.
-
Support of up to two Agilent Quick-Change valves within the Flexible Cube, also for advanced valve applications.
-
Selectable flush-times and variations of solvents (up to 3) may be utilized.
-
Flush pumps operate at pressures of up to 50 bar and flow rates of up to 4 mL/min.
-
Supported by Agilent chromatographic data systems and 3rd party data systems with the Agilent Instrument Control Framework (ICF)
