Agilent 7890A-7000A Triple Quadrupole GC/MS System (Refurbished)

Overview

The Agilent 7890A-7000A Triple Quadrupole GC/MS System is a fully refurbished, factory-tested benchtop analytical platform engineered for high-sensitivity, quantitative trace analysis in regulated and research-intensive laboratories. This system integrates the Agilent 7890A gas chromatograph — featuring advanced electronic pressure control (EPC), split/splitless injection, and programmable temperature vaporizing (PTV) inlet compatibility — with the Agilent 7000A triple quadrupole mass spectrometer, which employs collision cell technology (Q2) and fast polarity switching to deliver robust selectivity and low-pg-level detection limits for targeted analytes. The core measurement principle relies on electron ionization (EI) or chemical ionization (CI) followed by mass filtering in Q1, fragmentation in the RF-only collision cell (Q2), and selective detection in Q3 — enabling true multiple reaction monitoring (MRM) with high duty cycle and minimal cross-talk. Designed for compliance-critical environments, the system supports method validation workflows aligned with EPA Method 8270D, ASTM D7622, ISO 17025, and FDA 21 CFR Part 11 requirements when configured with appropriate software and audit trail modules.

Key Features

• Refurbished and performance-verified per Agilent’s pre-owned instrument standards: full vacuum integrity test, detector gain calibration, mass axis alignment, and retention time stability assessment across ≥50 compounds.
• Triple quadrupole architecture delivering <1 pg on-column limit of quantitation (LOQ) for pesticides, PAHs, and pharmaceutical impurities under MRM mode.
• 7890A GC equipped with dual EPC modules, 16-position autosampler (G4513A), and optional cryo-cooling for extended temperature ramping (−20 °C to 450 °C).
• 7000A MS featuring high-efficiency ion source, low-noise electron multiplier, and rapid polarity switching (<20 ms) for simultaneous positive/negative ion analysis.
• Robust mechanical design with stainless-steel ion optics, ceramic insulators, and sealed RF drive electronics ensuring long-term signal stability over 6–8 years of continuous operation.
• Comprehensive refurbishment includes replacement of consumables: column nut seals, septa, liner O-rings, ion source components, and detector assembly; all documented in the Certificate of Refurbishment.

Sample Compatibility & Compliance

The system accommodates volatile and semi-volatile organic compounds (VOCs/SVOCs) across environmental, clinical, food safety, and pharmaceutical matrices — including water extracts, soil leachates, plasma supernatants, and solvent-based residue samples. Sample introduction is compatible with standard 0.25–0.53 mm ID fused silica capillary columns (e.g., DB-5ms, HP-5MS, Rtx-1701). All hardware and firmware revisions meet RoHS 2011/65/EU directives and are compatible with Agilent’s OpenLab CDS 2.x software for GLP/GMP-compliant data acquisition. When deployed with electronic signatures, audit trails, and user access controls enabled, the configuration satisfies FDA 21 CFR Part 11 and EU Annex 11 expectations for regulated QC labs.

Software & Data Management

The system ships with Agilent MassHunter Workstation Software (Quantitative Analysis B.08.00 or later), supporting automated MRM method setup, batch processing, calibration curve generation (linear, quadratic, weighted), and integrated reporting templates compliant with ISO/IEC 17025 Clause 7.8. Raw data files (.d format) are natively supported for reprocessing, spectral deconvolution, and library searching against NIST MS Search 2.4 and Wiley Registry. Optional upgrades include MassHunter Quantitative Analytics with Advanced Reporting (QAR) for multi-instrument trending and LIMS integration via ASTM E1384-compliant XML export.

Applications

• Environmental testing: Quantification of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), brominated flame retardants (BFRs), and dioxin-like compounds in soil, sediment, and wastewater per EPA SW-846 Methods.
• Food safety: Multi-residue screening of mycotoxins (e.g., aflatoxin B1), veterinary drug residues (e.g., sulfonamides, tetracyclines), and process contaminants (e.g., furan, acrylamide) at EU MRL levels.
• Pharmaceutical QC: Residual solvent analysis (ICH Q3C), genotoxic impurity verification (ICH M7), and extractables/leachables profiling from packaging materials.
• Clinical toxicology: Targeted quantification of drugs of abuse (e.g., opioids, benzodiazepines) and metabolites in urine and blood using isotopically labeled internal standards.
• Forensic chemistry: Confirmation and quantification of controlled substances in seized materials with forensic-grade specificity and reproducibility (RSD <5% across 20 injections).

FAQ

What documentation accompanies the refurbished system?
A full Certificate of Refurbishment, detailed service history log, vacuum integrity report, mass calibration certificate, and factory acceptance test (FAT) summary are provided.
Is the system eligible for Agilent Care extended service contracts?
Yes — refurbished 7890A-7000A systems qualify for Agilent’s PlatinumCare or GoldCare contracts upon successful installation verification and registration.
Can this system be upgraded to support GC/MS/MS with newer software versions?
All 7000A instruments support MassHunter B.09.00+ and are compatible with current Agilent GC/MS/MS method libraries and spectral databases without hardware modification.
What is included in the 12-month warranty?
Coverage includes parts, labor, and on-site engineer dispatch for failures attributable to material or workmanship defects; excludes consumables, misuse, or unauthorized modifications.
How is system performance validated prior to shipment?
Each unit undergoes a standardized 48-hour operational stress test using a certified 50-component tuning mix, followed by sensitivity verification (1 pg injected OFN, S/N ≥ 500:1 in SIM mode) and retention time precision assessment (RSD ≤ 0.05% across 10 injections).
