Agilent 1100 Series Used Liquid Chromatograph (Quaternary/Binary Pump Configuration)

Overview

The Agilent 1100 Series Liquid Chromatograph is a robust, modular high-performance liquid chromatography (HPLC) platform originally engineered by Agilent Technologies in the United States. This used instrument retains full operational integrity and is validated for routine analytical applications across pharmaceutical QC, environmental testing, food safety, and academic research laboratories. Its architecture follows classical HPLC principles—employing high-pressure solvent delivery, precise sample introduction via autosampling, thermally controlled column elution, and selective detection based on UV-Vis absorbance, fluorescence, refractive index, or mass spectrometric response. The system’s modularity allows configuration as either a binary or quaternary gradient system, enabling method flexibility for isocratic, linear, or multi-step gradient separations. All core modules—including pumps, autosamplers, detectors, column ovens, and degassers—are interoperable under Agilent ChemStation or OpenLab CDS software control, ensuring reproducible retention time alignment and peak integration accuracy.

Key Features

• Modular design supporting field-upgradable configurations: binary pump, quaternary pump, or preparative-capable high-pressure pump options
• Electronically controlled flow (EFC) technology in quaternary/binary pumps ensures <0.1% RSD flow precision across 0.001–10 mL/min range
• Autosampler variants include standard, microplate-compatible (96-/384-well), and temperature-controlled models (4–40 °C, 1 °C increments)
• Detection versatility: Variable Wavelength Detector (VWD), Multi-Wavelength Detector (MWD), Diode Array Detector (DAD), Fluorescence Detector (FLD), Refractive Index Detector (RID), Electrochemical Detector (ECD), and optional LC/MS quadrupole or ion trap interfaces
• Column compartment maintains stable thermal environment from 10 °C below ambient to 80 °C, critical for retention time reproducibility
• Vacuum-based online degasser minimizes baseline noise and bubble formation during gradient elution
• Integrated diagnostics and self-monitoring functions reduce downtime and support predictive maintenance planning

Sample Compatibility & Compliance

The Agilent 1100 accommodates a broad spectrum of sample matrices—including aqueous extracts, organic solvents, biological fluids, and formulated drug products—when paired with appropriate column chemistries (e.g., C18, phenyl-hexyl, HILIC, or ion-exchange). It meets foundational requirements for compliance-driven workflows: hardware-level security controls, user-access logging, and data integrity safeguards align with ALCOA+ principles. When operated with Agilent OpenLab CDS and configured with electronic signature enforcement, the system satisfies FDA 21 CFR Part 11, EU Annex 11, and ISO/IEC 17025 documentation standards. Routine IQ/OQ protocols are supported via vendor-provided qualification kits, and all detectors conform to relevant ASTM methods (e.g., ASTM D7097 for hydrocarbon analysis, ASTM E2919 for pharmaceutical impurity profiling).

Software & Data Management

Data acquisition and processing rely on Agilent ChemStation (legacy) or OpenLab CDS (current-generation), both offering intuitive graphical interface navigation, customizable reporting templates, and batch sequence automation. Raw data files (.D format) are stored in structured directories with embedded metadata (instrument parameters, timestamps, user IDs). Audit trail functionality logs all method modifications, result reprocessing events, and user logins—enabling full traceability for regulatory inspections. Integration with LIMS platforms is achieved via standard ODBC or REST API connectors. Backups adhere to 3-2-1 policy recommendations: local SSD storage, network-attached RAID array, and offsite encrypted archive.

Applications

• Pharmaceutical quality control: assay quantitation, related substances testing, dissolution profile analysis per USP & EP monographs
• Environmental monitoring: pesticide residue screening in water/soil extracts using EPA Method 531.1 or 8081B
• Food & beverage analysis: caffeine, preservatives, sweeteners, and mycotoxins per AOAC and ISO 21569 protocols
• Academic research: natural product isolation verification, polymer molecular weight distribution (with SEC columns), and metabolomics profiling
• Clinical toxicology: therapeutic drug monitoring (TDM) and forensic screening of opioids, benzodiazepines, and stimulants

FAQ

Is this unit fully refurbished and performance-verified?
Yes. Each Agilent 1100 system undergoes comprehensive functional testing—including pressure stability, gradient accuracy, detector linearity, and autosampler precision—against original factory specifications prior to resale.
Does it include original Agilent software licenses?
No. Software licenses are not transferable under Agilent’s End User License Agreement. Customers must procure valid OpenLab CDS or ChemStation licenses directly from Agilent or an authorized distributor.
Can I integrate this with modern mass spectrometers?
Yes. The LC-1100 features standard analog/digital I/O and RS-232 interfaces compatible with third-party MS systems. For native LC/MS operation, the original Agilent MSD or Trap MSD modules may be included if specified at purchase.
What maintenance support is available post-purchase?
A 1-year parts-and-labor warranty is included. Extended service plans and on-site technical support are available through our global network of certified field engineers.
Are consumables and spare parts still available?
Yes. Agilent continues to supply critical spares—including pump seals, check valves, autosampler rotors, and lamp assemblies—for the 1100 series through its official distribution channels.
