Agilent LC Autosampler — Precision Meets Automation
Agilent Technologies has long been recognized for its robust and innovative liquid chromatography (LC) systems. The Agilent LC autosampler, a pivotal component of both analytical and preparative workflows, embodies the intersection of automation, precision, and reliability. For high-throughput laboratories, the 1260 Infinity II Preparative Autosampler pushes scalability further, accommodating up to 132 vials (2–6 mL each) and injection volumes up to 5 mL. It supports flow rates up to 200 mL/min at 400 bar, making it ideal for preparative purification workflows. The 1260 Infinity II Vialsampler is one of Agilent’s prominent autosamplers. Designed for routine pharmaceutical, environmental, and food analysis, it offers injection volumes from 0.1 to 900 µL, houses up to 100 × 2 mL vials in two trays, and supports operating pressures up to 40 MPa (400 bar). Integrated temperature control—from 4 °C to 80 °C—ensures sample stability, while compatibility with OpenLab CDS software streamlines data handling.

Tailored for high-throughput analytical applications, it offers programmed injections between 0.1–100 µL, extendable to 1,500 µL via hardware modifications. Precision performance remains high—< 0.25 % RSD for 5–100 µL injections—and carry-over is low, around < 0.1 %, dropping to < 0.05 % with external needle cleaning. It can handle 100 × 2 mL vials (full tray) or smaller trays and supports viscosities up to 50 cp, with optional Peltier-controlled thermostatic trays for 4–40 °C temperature control These autosamplers embody automation and efficiency—programmed injection cycles reduce manual workload, high vial capacities enable extended unattended operation, and their rugged flow-through designs minimize sample waste and carryover. With temperature control, precise metering, and broad volume ranges, Agilent autosamplers cater to diverse lab needs, from routine QC to high-throughput screening.
