Agilent 1100 Series Used HPLC System

Overview

The Agilent 1100 Series HPLC system—introduced in 1995 and engineered for robustness, modularity, and analytical reproducibility—represents a foundational platform in modern liquid chromatography. As a high-performance, pressure-driven separation system, it operates on the principle of differential partitioning of analytes between a mobile phase (liquid solvent gradient or isocratic eluent) and a stationary phase (packed capillary or analytical column), enabling precise retention time-based identification and quantification. Designed for laboratory environments requiring long-term operational stability and method transfer compatibility, the 1100 architecture supports both isocratic and gradient elution, with pressure capabilities up to 400 bar and flow rate precision within ±0.1% RSD. Its modular design allows flexible configuration across pump types (binary, quaternary, isocratic), detection modalities (UV-Vis, DAD, fluorescence, RI), and sample introduction methods (autosamplers with temperature control, capillary or preparative variants). Though superseded by newer generations (e.g., 1200/1260/1290 series), the 1100 remains widely deployed in QC labs, academic core facilities, and contract research organizations due to its proven reliability, extensive method library support, and broad regulatory acceptance.

Key Features

• Modular architecture supporting binary (G1312A) and quaternary (HP 1050) pump configurations with integrated vacuum degassing (G1322A or G1379A)
• Diode Array Detector (G1315B) delivering full-spectrum acquisition from 190–950 nm with 1 nm resolution and real-time peak purity analysis
• Thermostatted autosampler (G1329A) maintaining sample integrity at 4–40 °C with <±0.5 °C stability and low carryover (<0.005%)
• Column oven (G1316A) providing precise thermal control (5–80 °C) for retention time reproducibility and method robustness
• Embedded diagnostics and self-test routines compliant with Agilent ChemStation software architecture
• Full hardware compatibility with legacy and updated ChemStation versions (A.03.x through B.04.x), supporting audit trail and electronic signature features per FDA 21 CFR Part 11 when configured with appropriate user access controls

Sample Compatibility & Compliance

The Agilent 1100 accommodates standard 4.6 mm × 150 mm analytical columns as well as narrow-bore (2.1 mm ID), microbore (1.0 mm ID), and capillary formats (0.3 mm ID) via optional flow-cell adapters. It supports aqueous, organic, and mixed mobile phases—including TFA, HFBA, and ion-pair reagents—within pH 1.5–12.0 limits for silica-based columns. All refurbished units undergo full functional validation per ISO/IEC 17025-aligned internal protocols, including baseline noise assessment (<±0.5 mAU), retention time repeatability (<0.15% RSD over 10 injections), and detector linearity verification (r² ≥ 0.999 across 3 orders of magnitude). Systems are delivered with documentation packages suitable for GLP/GMP environments, including calibration certificates, performance qualification (PQ) reports, and traceable maintenance logs.

Software & Data Management

Operation is managed through Agilent ChemStation, a validated chromatography data system (CDS) supporting method development, sequence execution, peak integration, and report generation. The software enables secure user role management, electronic signatures, and audit trail activation—essential for regulated environments adhering to USP , ASTM E2500, and EU Annex 11 requirements. Data files (.D files) are stored in proprietary but fully exportable formats (CSV, ASCII, AIA), facilitating integration with LIMS platforms and third-party chemometric tools. All refurbished systems ship with licensed ChemStation software (B.04.03 or later), pre-installed on a Windows 10 Pro workstation with dual-monitor support and backup SSD storage.

Applications

The Agilent 1100 serves diverse analytical workflows: small-molecule pharmaceutical assay (USP ), residual solvent testing (ICH Q3C), peptide mapping under denaturing conditions, natural product fingerprinting, polymer additive quantification, and environmental contaminant screening (EPA Method 8330B). Its stable gradient formation and low dwell volume (<1.0 mL) make it particularly suitable for method transfer from older HP 1050/1100 platforms and for validation studies requiring historical comparability. Academic users leverage its open architecture for custom method scripting and detector synchronization experiments; industrial QA labs rely on its deterministic pump behavior for routine release testing where inter-instrument consistency is critical.

FAQ

Is this system eligible for IQ/OQ/PQ documentation support?
Yes—full installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) documentation packages are available upon request, aligned with ASTM E2500 and GAMP5 guidelines.
Can I upgrade the detector post-purchase?
All detector modules (VWD, DAD, FL, RI) are hot-swappable and retain full firmware compatibility with the 1100 controller; upgrades require only mechanical installation and software recognition.
What warranty coverage applies to refurbished components?
Each instrument carries a 6-month comprehensive parts-and-labor warranty, extendable to 12 months with optional service agreement; all detectors, pumps, and autosamplers are tested to original Agilent specifications prior to shipment.
Does the system include method validation templates?
Standard operating procedures (SOPs) and blank validation templates compliant with ICH Q2(R2) are provided, covering specificity, linearity, accuracy, precision, LOD/LOQ, and robustness assessments.
Are consumables and spare parts still available?
Yes—Agilent continues to supply genuine seals, pistons, gaskets, lamp assemblies, and flow cells for the 1100 series; we maintain an on-hand inventory of critical spares and offer lifetime technical support for hardware troubleshooting.
