Agilent 1260 Infinity II Liquid Chromatography System

Overview

The Agilent 1260 Infinity II Liquid Chromatography System is a modular, high-performance HPLC platform engineered for robustness, reproducibility, and method transfer fidelity across routine QC, pharmaceutical development, and academic research environments. Built on Agilent’s InfinityLab architecture, it supports both conventional HPLC and UHPLC-compatible workflows—operating reliably at pressures up to 600 bar (with select pump modules rated to 800 bar) and delivering precise gradient formation, low carryover, and thermally stable column conditioning. Its modular design enables configuration flexibility: users may integrate quaternary or binary pumping, multisampling, high-capacity column ovens, and a range of detectors—including DAD HS, MWD, VWD, fluorescence, and ELSD—each optimized for sensitivity, linearity, and compliance-ready data integrity.

Key Features

• Modular Pump Architecture: The 1260 Infinity II Quaternary Pump (G7112B) delivers flow rates from 0.05–5 mL/min at ≤600 bar; the Binary Pump (G7110B/G7111A/B) extends flow range to 0.2–10 mL/min and supports LC/MS-coupled methods requiring rapid, low-delay gradient precision.
• Ultra-Low Carryover: The 1260 Infinity II Multisampler employs triple-solvent needle seat backflush and full-path wash protocols, achieving residual levels <10 ppm—critical for trace analysis and regulated bioanalysis.
• Dual-Needle Sample Introduction: Enables alternating injection cycles between two independent channels, reducing cycle time to seconds and eliminating idle wait states during large-volume injections or column equilibration.
• High-Capacity Sample Handling: Accommodates up to 16 microtiter plates (384-well) or 6144 discrete samples in a single run—ideal for high-throughput screening and biopharma stability studies.
• Advanced Column Management: The high-capacity column compartment (G7116A/B) maintains temperature control from −10 °C to 85 °C and houses up to four columns with Quick Change valve integration—enabling automated column switching without manual tubing disconnection.
• Detector Versatility: Includes DAD HS (190–640 nm, 120 Hz), DAD WR (190–950 nm), MWD (8 simultaneous wavelengths), VWD (±2.5 µAU/cm noise), fluorescence (74–148 Hz spectral acquisition), and high-temperature ELSD—all compliant with signal sampling and dynamic range requirements of ICH Q2(R2) and USP <621>.

Sample Compatibility & Compliance

The system accommodates standard 1.8–4.6 mm ID analytical columns, including Poroshell 120 and other sub-2-µm particle packings. It supports aqueous, organic, and ion-pairing mobile phases with up to four solvent channels (expandable via Solvent Selection Valve). All hardware modules meet CE, UL, and CSA safety standards. Data acquisition and instrument control comply with FDA 21 CFR Part 11 when used with Agilent OpenLab CDS or third-party CDS platforms supporting electronic signatures, audit trails, and role-based access control. System qualification documentation—including IQ/OQ/PQ templates—is provided per GMP/GLP expectations. The platform holds My Green Lab ACT certification, verifying lifecycle environmental impact transparency per ISO 14040/14044.

Software & Data Management

Instrument control is managed via Agilent Instrument Control Framework (ICF), enabling seamless integration with Agilent OpenLab CDS, ChemStation, or validated third-party chromatography data systems. ICF supports remote diagnostics, real-time signal plotting, and event-triggered logging. Optional InfinityLab Companion provides local web-based monitoring, basic troubleshooting, and waveform visualization without full CDS licensing. Buffer Advisor software assists in pH and ionic strength optimization for ion-exchange and charge variant analysis—supporting Design of Experiments (DoE) workflows. All detector data are stored in vendor-neutral formats (e.g., .agilent, .cdf) compatible with LIMS and statistical analysis tools.

Applications

The Agilent 1260 Infinity II serves diverse applications: small-molecule impurity profiling per ICH Q3B, peptide mapping under denaturing conditions, oligonucleotide purity assessment, natural product fingerprinting, excipient compatibility testing, and forced degradation studies. Its dual-pump gradient capability and thermal column management make it suitable for method development involving temperature- and pH-sensitive separations. The high-pressure tolerance and low dispersion design support method transfer from UHPLC to HPLC without re-optimization. In QC labs, its 1-year warranty and documented service history (10-year operational life) ensure predictable cost-of-ownership and minimal downtime.

FAQ

Is this unit fully refurbished and performance-verified?
Yes—each 1260 Infinity II system undergoes full functional validation per Agilent’s Used Equipment Certification Protocol, including pressure leak testing, gradient accuracy verification, detector linearity assessment, and autosampler precision evaluation.
Does it include original Agilent software licenses?
The system ships with factory-installed firmware and driver packages; perpetual CDS licenses are not included but can be acquired separately through Agilent or authorized partners.
Can it be integrated into an existing OpenLab CDS network?
Yes—the instrument supports Ethernet-based communication via ICF and is compatible with OpenLab CDS 2.x and later versions when configured with appropriate security certificates and user roles.
What maintenance records are available?
Full service history—including PM logs, component replacements, and calibration certificates—is provided upon request, subject to data retention policies of the prior operator.
Is column oven pre-heating and cooling rate specified?
The high-capacity column compartment achieves temperature stabilization within ±0.15 °C over the range −10 °C to 85 °C; ramp rates are programmable and typically 0.1–1.0 °C/min depending on setpoint delta and ambient conditions.
