Agilent 7890A Gas Chromatograph with 5975C Triple-Axis Inert MSD

Overview

The Agilent 7890A Gas Chromatograph coupled with the 5975C Mass Selective Detector (MSD) represents a mature, field-proven platform for high-fidelity qualitative and quantitative analysis of volatile and semi-volatile organic compounds. Engineered for precision, reproducibility, and robustness in regulated and research environments, this GC/MS system operates on electron ionization (EI) and optional chemical ionization (CI) modes, delivering reliable spectral acquisition, library-searchable mass spectra, and trace-level detection sensitivity. The 7890A GC features advanced pneumatic control, split/splitless injection, programmable temperature vaporizing (PTV) injector compatibility, and a high-stability oven capable of ramp rates up to 120 °C/min. The 5975C MSD incorporates an inert triple-axis detector architecture—optimized for reduced surface adsorption of active analytes—including deuterated filaments, high-capacity vacuum pumps, and a quadrupole mass analyzer with unit-mass resolution across m/z 10–800. This configuration ensures consistent performance for applications ranging from environmental contaminant screening to residual solvent analysis in pharmaceuticals.

Key Features

• Agilent 7890A GC platform with electronic pressure control (EPC), dual-channel capability, and support for up to three detectors
• 5975C Inert MSD featuring triple-axis detector geometry, low-bleed inert column interface, and enhanced signal-to-noise ratio
• Pre-installed and validated ChemStation software (G1701EA E.02.x or later) enabling full scan, selected ion monitoring (SIM), and automated tune/report generation
• Fully refurbished and functionally verified by SpectraLab Scientific’s certified service engineers—including leak testing, detector tuning, and retention time calibration
• Includes dedicated workstation PC with preloaded software, licensed operating system, and validated instrument control drivers
• Compliant with ASTM D3699 (hydrocarbon solvents), EPA Method 8260C (volatile organics), and USP chromatographic system suitability requirements

Sample Compatibility & Compliance

This GC/MS system accommodates standard 0.25–0.53 mm ID fused-silica capillary columns (e.g., DB-5ms, HP-5MS, VF-WAXms) and supports common sample introduction methods: split, splitless, PTV, and direct aqueous injection. It is routinely deployed for analysis of pesticides, PAHs, PCBs, VOCs, residual solvents (ICH Q3C), and flavor/aroma compounds. All refurbished units undergo GLP-aligned documentation—each instrument ships with a Certificate of Reconditioning, system verification report (including retention time reproducibility, peak area RSD ≤ 3%, and mass calibration accuracy ±0.1 Da), and audit-ready maintenance logs. The configuration meets baseline requirements for FDA 21 CFR Part 11 compliance when deployed with appropriate electronic signature and audit trail configurations.

Software & Data Management

Controlled via Agilent ChemStation software (E.02.x series), the system supports method development, sequence execution, real-time data acquisition, and post-run processing—including spectral deconvolution (AMD), compound identification using NIST/EPA/NIH mass spectral libraries, and customizable reporting templates. Data files (.D directories) are stored in vendor-native format with embedded metadata (instrument parameters, tune settings, acquisition timestamps). SpectraLab provides software installation verification, license transfer assistance (where permitted), and optional training on data review workflows, integration with LIMS interfaces (via OpenLab CDS export), and routine system suitability testing protocols.

Applications

• Environmental testing: Analysis of chlorinated hydrocarbons, BTEX, phthalates, and emerging contaminants per EPA SW-846 and ISO 17993
• Pharmaceutical QC: Residual solvent quantification (Class 1–3) aligned with ICH Q3C guidelines and USP
• Food & flavor safety: Detection of mycotoxins, pesticide residues, and adulterants using SIM and confirmatory MS/MS transitions
• Polymer & materials science: Extractables/leachables profiling from packaging, medical devices, and elastomers
• Forensic toxicology: Screening and confirmation of drugs of abuse and metabolites in biological matrices

FAQ

Is this system supplied with original Agilent documentation and software licenses?
Yes—each unit includes original hardware documentation, ChemStation software media (or digital license key), and a valid Certificate of Reconditioning issued by SpectraLab Scientific.
What level of technical support is included post-purchase?
SpectraLab provides remote troubleshooting, application consultation, and access to certified field service engineers for on-site support under the 6-month warranty period.
Can this GC/MS be upgraded to support GC/MS/MS functionality?
No—the 5975C is a single-quadrupole MSD; tandem MS capability requires replacement with a 7000-series triple quadrupole system or equivalent.
Are consumables (columns, septa, liners, filaments) available through SpectraLab?
Yes—we maintain inventory of genuine Agilent consumables and offer bundled starter kits tailored to your analytical workflow.
Does the refurbishment include replacement of critical wear components?
Yes—standard refurbishment includes new inlet seals, gold-plated ferrules, detector filaments, pump oil, and vacuum pump rebuild where applicable.
