Overview
The Agilent 7890A-5975C Gas Chromatography-Mass Spectrometry (GC-MS) system is a robust, benchtop analytical platform engineered for high-sensitivity qualitative and quantitative analysis of volatile and semi-volatile organic compounds. This configuration 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 5975C inert triple-axis quadrupole mass selective detector (MSD). The system operates on electron ionization (EI) mode with optional chemical ionization (CI) capability, delivering reliable spectral reproducibility, linear dynamic range exceeding 10⁶, and detection limits in the low femtogram range for target analytes under optimized conditions. Designed for routine laboratory environments, the 7890A-5975C supports method transfer across Agilent GC-MS platforms and maintains full backward compatibility with ChemStation software workflows.
Key Features
- Agilent 7890A GC module with dual EPC channels, enabling precise, repeatable carrier gas flow and pressure control across temperature gradients
- 5975C MSD equipped with an inert ion source, high-efficiency extractor lens assembly, and triaxial detector geometry for enhanced signal-to-noise ratio and reduced background interference
- Auto-tune functionality compliant with ASTM D5845 and EPA Method 8270D performance criteria
- Integrated hardware diagnostics and real-time status monitoring via front-panel LED indicators and ChemStation event logs
- Refurbished and functionally validated per Agilent-recommended protocols; CE marking confirmed post-refurbishment per EU Directive 2014/30/EU (EMC) and 2014/35/EU (LVD)
- No original manufacturer warranty; full operational verification conducted by SpectraLab Scientific prior to listing
Sample Compatibility & Compliance
The system accommodates standard 1/4″ or 1/8″ GC columns (e.g., DB-5ms, HP-5MS, VF-WAXms) and supports common sample introduction techniques including liquid autosampling (via Agilent G1888 or PAL systems), headspace analysis (with compatible HS units), and thermal desorption (when interfaced with appropriate TD modules). It meets essential regulatory requirements for environmental, food safety, and forensic applications: fully compatible with U.S. EPA Methods 502.2, 524.2, 8260C, and 8270D; aligned with ISO 17025 documentation practices for instrument qualification; and capable of supporting GLP-compliant data acquisition when operated with audit-trail-enabled ChemStation configurations (subject to local IT validation protocols).
Software & Data Management
Controlled exclusively through Agilent ChemStation E.02.02.x or later (Windows 7/10 64-bit), the system supports both single-quadrupole scan/SIM acquisition modes, library search (NIST MS Search 2.0g integrated), and automated report generation. Raw data files (.D format) are structured for long-term archival and interoperability with third-party processing tools (e.g., AMDIS, MassHunter Quantitative Analysis). While FDA 21 CFR Part 11 compliance is not inherent to the base ChemStation installation, it can be achieved through site-specific configuration of electronic signatures, user access controls, and audit trail activation — all documented within the laboratory’s SOPs and validation master plan.
Applications
This GC-MS system is routinely deployed in environmental testing laboratories for pesticide residue screening in soil and water matrices; in pharmaceutical QC labs for residual solvent analysis per ICH Q3C guidelines; in food and beverage facilities for flavor compound profiling and contaminant identification (e.g., PAHs, mycotoxins); and in academic research settings for metabolite fingerprinting in plant extracts or polymer degradation product characterization. Its proven stability over 3–4 years of continuous operation — verified through repeated retention time locking (RTL) and tune-report consistency — makes it suitable for mid-throughput laboratories requiring dependable, cost-optimized instrumentation without compromising analytical rigor.
FAQ
Is this instrument eligible for Agilent factory service contracts?
No — as a second-hand unit with no remaining original warranty, it is not eligible for Agilent Care or Priority Support programs. Third-party service agreements may be arranged independently.
What documentation accompanies the system?
A full functional test report from SpectraLab Scientific, CE conformity statement post-refurbishment, electrical safety certification summary, and calibrated reference tune report are provided.
Can the 5975C MSD be upgraded to a 5977-series detector?
No — the 5975C chassis is mechanically and electrically incompatible with newer 5977-series detectors. Detector replacement requires full GC-MS platform migration.
Does the system include a computer and software license?
No — ChemStation software licensing and host PC hardware must be procured separately and validated per local IT security policies.
What maintenance history is available?
SpectraLab’s pre-delivery assessment includes column oven calibration verification, ion source cleaning log, filament replacement status, and vacuum system leak-check results — all summarized in the final inspection report.
