Description
The Agilent 1290 Infinity Autosampler (Model G4226A) is a high-performance UHPLC sample injection module designed for ultrafast, high-pressure liquid chromatography separations. Operating at system pressures up to 1200 bar, it delivers ultra-low carryover, precise injection volumes, and rapid injection cycle times. Featuring a flow-through design with dynamic needle wash capabilities and flexible sample capacity (microplates, vial plates, or standard 2 mL vials), the G4226A integrates seamlessly into Agilent 1260 and 1290 Infinity LC stacks.
Features:
-
1200 Bar High-Pressure Operation: Supports high-pressure UHPLC applications without compromising injection precision or system durability.
-
Flow-Through Injection Architecture: Minimizes internal dead volume and extra-column peak broadening for sharp chromatographic peaks.
-
Ultra-Low Carryover: Flow-through design paired with active exterior needle washing drastically reduces sample contamination between runs.
-
Broad Injection Volume Range: Supports injection volumes from 0.1 uL up to 40 uL (expandable up to 900 uL with extension loops).
-
Versatile Sample Capacity: Holds up to 2 standard microplates/deep-well plates, or up to 108 standard 2 mL sample vials.
-
Temperature Control Compatible: Fully compatible with the optional Agilent 1290 Infinity Thermostat (G1330B) for sample cooling down to 4°C.
