Description

Agilent 1290 Infinity G4226A Sampler Overview

The Agilent 1290 Infinity G4226A Sampler is a high-pressure autosampler rated up to 1200 bar, engineered for ultrafast, high-precision sample injection with typical carryover under 0.004%. Its next-generation flow-through design uses only the exact injected volume from each sample, with no loop-changing required across a 0.1–20 µL injection range in 0.1 µL increments.

An X-Z-theta robotic transport mechanism, driven by stepper motors with optical encoders, delivers precise, repeatable sample positioning across vials and well plates. A dedicated needle flush station rinses the needle exterior between injections to further reduce carryover, while a vial and plate pusher mechanism stabilizes sample containers during needle withdrawal.

The G4226A supports overlapped injection mode for higher sample throughput, with a typical injection cycle time under 21 seconds. It handles a range of sample formats — including 2 mL and 6 mL vials and microtiter well plates — accommodating up to 768 unattended samples when configured with 384-well plates.

This Agilent 1290 Infinity G4226A Sampler is offered fully refurbished and tested, in working condition, by Alliant Scientific.
