What Agilent 1260 Infinity II LC chromatograph is and how it works

The Agilent 1260 Infinity II LC chromatograph is an integrated high performance liquid chromatography platform designed for routine to advanced analytical applications in liquid phase separationAgilent, 10/2023.

The system typically combines a pump, autosampler, column compartment, and detector in a modular stack that can be configured for tasks such as pharmaceutical assay development and quality control testingAgilent, 10/2023Agilent, 11/2023.

Liquid chromatography works by pumping a mixture of solvent and sample through a column packed with stationary phase material, where different analytes interact differently with the packing and separate as they move through the systemFDA, 08/2023LCGC North America, 04/2023.

In the 1260 Infinity II LC, an autosampler introduces precisely metered sample volumes into the flowing mobile phase stream, which then passes through the column and into detectors such as diode array or fluorescence modules to generate chromatogramsAgilent, 10/2023Agilent, 03/2024.

The platform is part of Agilent's InfinityLab LC Series, which is built around common hardware, software, and consumables to support consistent performance and simplified maintenance in multi-instrument laboratoriesAgilent, 11/2023Agilent, 01/2024.
