Agilent 5975T LTM GC/MSD System (Refurbished)

Overview

The Agilent 5975T LTM GC/MSD is a fully refurbished, laboratory-grade gas chromatography/mass spectrometry system engineered for high-performance volatile and semi-volatile organic compound analysis in both mobile and fixed-laboratory environments. As the industry’s first commercially available low-thermal-mass (LTM) GC/MS platform, it integrates Agilent’s proprietary LTM column module with a triple-axis detector-equipped mass selective detector (MSD), delivering analytical fidelity comparable to benchtop 5975-series instruments—while occupying approximately 30% less footprint. Its core measurement principle relies on electron ionization (EI) at 70 eV, followed by quadrupole mass filtering and electron multiplier detection across a mass range of m/z 1.8–1050. Designed to meet MIL-STD-810F shock and vibration specifications, the system maintains chromatographic integrity during transport and field deployment without recalibration, making it suitable for environmental monitoring, emergency response, forensic screening, and regulatory compliance testing where portability and reproducibility are co-dependent requirements.

Key Features

• Low-thermal-mass (LTM) GC architecture enabling rapid temperature ramping (up to 1200 °C/min) and cooling rates exceeding 600 °C/min—reducing cycle time without compromising peak resolution or sensitivity
• Robust vacuum system featuring a Pfeiffer two-stage turbomolecular pump with integrated backing pump, maintaining stable operating pressure (<1×10⁻⁵ Torr) under dynamic thermal load
• Triple-axis detector configuration optimized for signal-to-noise ratio enhancement and long-term gain stability over extended operational cycles
• Modular inlet compatibility supporting multiple sample introduction techniques: liquid autosampler (ALS), thermal separation probe (TSP), solid-phase microextraction (SPME), thermal desorption (TD), headspace (HS), and purge-and-trap (P&T)
• Integrated electronics architecture with real-time data acquisition at ≥10 spectra/sec, ensuring full-scan fidelity for fast-eluting compounds

Sample Compatibility & Compliance

The 5975T LTM GC/MSD supports broad-spectrum analyte classes including pesticides, PCBs, PAHs, VOCs, SVOCs, hydrocarbons, and regulated contaminants per EPA Methods 502.2, 524.2, 8260D, 8270E, and ASTM D7011. It meets GLP-compliant operation when configured with audit-trail-enabled software and secure user access controls. While not pre-certified for FDA 21 CFR Part 11 out-of-the-box, the system is fully compatible with Agilent’s MassHunter Workstation when deployed with validated configurations—including electronic signatures, data integrity logging, and role-based permissions—enabling alignment with GMP and ISO/IEC 17025 quality management frameworks.

Software & Data Management

Data acquisition and processing are performed using Agilent MassHunter Qualitative and Quantitative Analysis software (v10.x or later), supporting spectral library searching (NIST, Wiley), automated deconvolution of co-eluting peaks via AMDIS, and customizable report generation. The DRS/RTL database extension enables multi-target compound identification through structured query logic, significantly reducing false-positive/negative rates in complex matrices. Raw data files (.D format) are stored in vendor-neutral formats compliant with ASTM E1947 and retain full traceability of acquisition parameters, calibration history, and instrument state metadata. All refurbished units undergo firmware validation to ensure compatibility with current MassHunter versions and security patch levels.

Applications

• Field-deployable environmental screening: soil vapor intrusion, landfill gas profiling, wastewater effluent monitoring
• First-responder chemical threat identification in hazmat incidents or CBRNE scenarios
• Forensic toxicology labs requiring rapid turnaround for volatile drug metabolites and accelerants
• Food safety laboratories performing residual solvent analysis per ICH Q3C guidelines
• Academic and contract research facilities seeking cost-effective access to high-resolution GC/MS capability without capital-intensive infrastructure upgrades

FAQ

Is this unit factory-refurbished or third-party refurbished?
This system has been comprehensively refurbished and performance-validated by SpectraLab Scientific, an Agilent-authorized service partner, following OEM-recommended procedures including detector cleaning, source replacement, vacuum integrity verification, and full-system calibration traceable to NIST standards.
What documentation accompanies the instrument?
Each unit ships with a Certificate of Refurbishment, detailed service history log, calibration report, and original Agilent technical manuals. Full electronic documentation is provided on encrypted USB media.
Can the system be upgraded to support newer software releases?
Yes—the hardware platform supports MassHunter v10.1 and later; upgrade paths require validation per ISO/IEC 17025 Section 5.4.2 prior to use in accredited testing environments.
Does the 6-month warranty cover consumables and labor?
The warranty includes parts, labor, and on-site service for defects in materials or workmanship. Consumables (e.g., columns, filaments, septa) are excluded but available at discounted rates through our spare parts program.
Is remote diagnostics supported?
Remote connectivity is enabled via secure TLS-encrypted VNC sessions, allowing authorized Agilent-certified engineers to perform health checks, firmware updates, and troubleshooting—subject to customer network policy approval.
