Agilent 7890B GC System with 5977A Single Quadrupole Mass Selective Detector (Used)

Overview

The Agilent 7890B Gas Chromatograph coupled with the 5977A Mass Selective Detector represents a fully integrated, high-performance gas chromatography–mass spectrometry (GC-MS) platform engineered for routine qualitative and quantitative analysis in environmental, pharmaceutical, food safety, and forensic laboratories. This used system retains the core architecture of Agilent’s flagship single quadrupole GC-MS design—featuring a thermally stable, precision-engineered GC oven, advanced pneumatic control (APC), and a high-efficiency source (HES) that optimizes ion generation, transmission, and detection efficiency. The 5977A MSD employs electron ionization (EI) as its primary ionization mode, delivering robust spectral reproducibility and library-searchable spectra compliant with NIST/EPA/ Wiley reference libraries. Its quadrupole mass analyzer operates across a mass range of 1.2–1050 u with unit mass resolution, enabling reliable identification and quantitation of volatile and semi-volatile organic compounds at trace levels.

Key Features

• Agilent 7890B GC: Dual independent temperature zones, programmable ramp rates up to 120 °C/min, column oven operating range from –10 °C to 450 °C (with liquid nitrogen cooling option), and built-in leak detection for method robustness.
• 5977A MSD: High Efficiency Source (HES) increases ion transmission by up to 10× compared to legacy EI sources, resulting in sub-femtogram IDL performance (e.g., 1.5 fg IDL for chlorobenzene).
• Inert flow path: Ultra-inert components—including deactivated transfer lines, gold-plated ion source, and low-bleed consumables—minimize analyte adsorption, degradation, and background contamination.
• IDP-3 dry scroll vacuum pump (if equipped): Oil-free operation ensures zero hydrocarbon backstreaming, reduces maintenance frequency, and enables near-silent laboratory integration.
• Integrated hardware synchronization: Precise timing alignment between GC elution and MS acquisition eliminates retention time drift and enhances peak fidelity during multi-method runs.

Sample Compatibility & Compliance

This GC-MS system is validated for analysis of volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), pesticides, polycyclic aromatic hydrocarbons (PAHs), phthalates, flame retardants, and residual solvents. It supports EPA Methods 502.2, 524.4, 8260D, 8270E, ASTM D7011, ISO 17993, and USP for chromatographic system suitability. When configured with MassHunter software and appropriate user access controls, the system supports 21 CFR Part 11 compliance—including electronic signatures, audit trails, and data integrity safeguards—making it suitable for regulated environments requiring GLP or GMP documentation.

Software & Data Management

Agilent MassHunter Workstation (v10.x or later) provides unified control of both GC and MS modules, from method setup and instrument calibration to automated data acquisition, processing, and reporting. Key capabilities include: real-time spectral deconvolution (AMDIS), quantitative batch processing with internal standard normalization, customizable report templates, and export to LIMS-compatible formats (e.g., .csv, .pdf, .mzML). All raw data files (.d format) are stored with full metadata, including instrument parameters, sequence logs, and calibration history—ensuring full traceability and long-term archival compliance.

Applications

• Environmental testing: Detection of VOCs in drinking water (EPA 524), SVOCs in soil/sediment (EPA 8270), and dioxins/furans in air emissions.
• Pharmaceutical QC: Residual solvent analysis per ICH Q3C guidelines; extractables and leachables profiling in packaging materials.
• Food safety: Pesticide multiresidue screening in fruits, vegetables, and animal tissues; mycotoxin verification.
• Forensic toxicology: Rapid confirmation of drugs of abuse and metabolites in biological matrices.
• Materials science: Outgassing analysis of polymers, adhesives, and electronic components under thermal desorption-GC-MS.

FAQ

Is this a refurbished or reconditioned system?
This is a pre-owned Agilent GC-MS system sourced directly from international laboratories; it undergoes functional verification and baseline performance testing prior to resale. Full service history and calibration records are available upon request.
Does the system include a valid MassHunter software license?
Yes—software licenses are transferable per Agilent’s End User License Agreement (EULA); activation requires Agilent CrossLab registration and may involve nominal administrative fees.
What maintenance documentation is provided?
Each unit ships with a completed Pre-Delivery Inspection (PDI) report, recent tune reports (e.g., autotune results), and a list of replaced consumables (e.g., column, liner, septum, filament, trap).
Can this system be upgraded to support SIM or selected ion monitoring?
Yes—the 5977A MSD natively supports full-scan, SIM, and targeted MS/MS (via optional hardware upgrade to 5977B or newer models); SIM methods can be developed and deployed immediately using MassHunter Quantitative Analysis.
Is on-site installation and qualification support available?
Agilent CrossLab-certified field engineers provide IQ/OQ services globally; third-party qualified vendors may also perform installation qualification under documented SOPs aligned with ISO/IEC 17025 requirements.
