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

Overview

The Agilent 7890A Gas Chromatograph coupled with the 7000B Triple Quadrupole Mass Spectrometer represents a rigorously refurbished, high-performance GC-MS/MS platform engineered for ultra-trace quantitative analysis in regulated and research laboratories. This system operates on the principle of electron ionization (EI) followed by two sequential mass filtering stages (Q1 → Q2 (collision cell) → Q3), enabling highly selective reaction monitoring (SRM) and multiple reaction monitoring (MRM) acquisition. Its architecture delivers exceptional signal-to-noise ratio, minimized chemical noise, and robust discrimination against matrix interferences—critical for applications including pesticide residue analysis in food and water, forensic toxicology in complex biological matrices, and persistent organic pollutant (POP) quantification in environmental samples. The 7890A GC contributes advanced flow control, rapid oven cooling (<220 °C/min), and full-flow path inertness (via Ultra Inert inlet liners, deactivated columns, and optimized detector interfaces), while the 7000B MS features a high-efficiency ion source, collision-cell-optimized quadrupole transmission, and low-noise electron multiplier detection—all calibrated and validated per Agilent’s factory refurbishment protocol.

Key Features

• Sub-femtogram (fg) limit of detection (LOD) and limit of quantitation (LOQ) under SRM conditions, verified with certified reference standards (e.g., chlorpyrifos, diazinon)
• Real-time MRM acquisition at dwell times as low as 1 ms and up to 500 transitions per second—maintaining sensitivity and reproducibility without memory effects in the collision cell
• 7890A GC with integrated Electronic Pressure Control (EPC), dual-channel capability, and optional third detector support (TCD/ECD) for method flexibility
• Full-system inertness: Ultra Inert inlet liners, deactivation-treated split/splitless injectors, and inert column connections minimize adsorption and degradation of labile analytes (e.g., organophosphates, steroids, fatty acid methyl esters)
• Agilent OpenLAB CDS software with 40× faster data processing, embedded method conversion calculators (He → H₂/N₂), and automated maintenance alerts (EMF)
• Sleep/Wake mode reduces power consumption by >60% during idle periods while preserving column conditioning and vacuum integrity
• Microfluidic Flow Technology (CFT) enables leak-free, in-oven capillary connections and rapid method transfer between instruments

Sample Compatibility & Compliance

This refurbished GC-MS/MS system is validated for use with liquid, solid, and gaseous samples following standard preparation protocols—including QuEChERS, SPE, SPME, and headspace sampling. It supports compliance with major international regulatory frameworks: EPA Methods 8270/8272 (semivolatiles), ASTM D7622 (petroleum hydrocarbons), ISO 17025–accredited laboratory workflows, and USP validation guidelines. When deployed with OpenLAB CDS configured for audit trail, electronic signatures, and user-access controls, the system meets FDA 21 CFR Part 11 requirements for data integrity in GLP and GMP environments. All consumables—including GC inlet seals, gold-plated ion source components, and collision gas filters—are sourced from Agilent-certified OEM suppliers and replaced during refurbishment.

Software & Data Management

The system ships with Agilent OpenLAB CDS v2.4 or later, pre-installed and licensed for full instrument control, data acquisition, peak integration, calibration curve generation, and report export (PDF, CSV, XML). The software includes built-in tools for method translation (e.g., helium-to-hydrogen carrier gas conversion), retention time locking (RTL), and automated QC check routines (e.g., tune report validation, background noise assessment). Audit trails record all user actions—including method edits, sequence changes, and raw data reprocessing—with timestamped, non-erasable entries. Data backups are supported via network-attached storage (NAS) or Agilent’s Secure Data Vault option. Remote diagnostics and firmware updates are enabled through Agilent’s authorized service portal—accessible only by certified engineers post-warranty.

Applications

• Food safety testing: Multi-residue screening of >300 pesticides in fruits, vegetables, and infant formula per EU SANTE/11312/2021 guidelines
• Environmental monitoring: Quantitative analysis of PCBs, dioxins, PAHs, and brominated flame retardants in soil, sediment, and wastewater
• Clinical & forensic toxicology: Targeted quantification of opioids, benzodiazepines, stimulants, and novel psychoactive substances (NPS) in blood, urine, and hair
• Pharmaceutical impurity profiling: Identification and quantification of genotoxic impurities (GTIs) at ≤1 ppm levels in drug substances
• Essential oil and flavor compound characterization: Structural confirmation via library matching (NIST/EPA/NIH) combined with retention index alignment

FAQ

What does “refurbished” mean for this Agilent GC-MS/MS system?
Refurbishment includes full disassembly, cleaning, replacement of all wear-prone components (ion source, detector, GC inlet seals, septa, liners, column nuts), recalibration against NIST-traceable standards, vacuum integrity verification, and comprehensive performance qualification (PQ) testing per Agilent’s Field Service Bulletin FSB-7000B-01.
Is the original Agilent warranty transferable?
No—the original manufacturer warranty expires upon first sale. This unit carries a 12-month limited warranty covering parts and labor for defects in materials or workmanship, administered directly by our ISO 9001–certified service team.
Can this system be upgraded to support newer software versions or hardware modules?
Yes. The 7890A GC and 7000B MS are backward- and forward-compatible with Agilent’s current OpenLAB CDS releases and optional accessories (e.g., PAL autosampler upgrades, JetClean ion source, 7010B upgrade kit). Upgrade paths are assessed case-by-case during pre-delivery consultation.
Do you provide IQ/OQ/PQ documentation?
Yes. Upon request, we supply customizable Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) protocols aligned with ISO/IEC 17025 and ASTM E2500 standards—executed on-site or remotely by certified field application scientists.
What is included in the delivery package?
The system ships with GC oven, MS detector, vacuum pump (turbo + backing), OpenLAB CDS workstation (Windows 10 Pro, 32 GB RAM, 1 TB SSD), Agilent-certified consumables starter kit, electronic manuals, and a signed Certificate of Refurbishment detailing all replaced parts and test results.
