Agilent Technologies 7820A-5975 GC-MS System (Refurbished)

Overview

The Agilent Technologies 7820A-5975 GC-MS System is a fully refurbished, factory-tested gas chromatography mass spectrometry platform engineered for reliable qualitative and quantitative analysis of volatile and semi-volatile organic compounds. This integrated system combines the robustness of the Agilent 7820A capillary gas chromatograph—with its precision electronic pressure control (EPC), split/splitless injection capability, and programmable temperature vaporizing (PTV) injector compatibility—with the proven performance of the Agilent 5975 Series mass selective detector (MSD). The 5975 MSD employs a single quadrupole mass analyzer operating in electron ionization (EI) mode, delivering high reproducibility across routine environmental, food safety, forensic, and pharmaceutical QC applications. Its mass range of 1.5–1050 amu supports broad compound coverage, while the scan speed of 10,000 u/s enables high-resolution peak definition in complex matrices without sacrificing duty cycle.

Key Features

• Refurbished and performance-validated by SpectraLab Scientific to meet original Agilent specifications for retention time stability, mass calibration accuracy, and signal-to-noise ratio.
• Agilent 7693A autosampler with 150-position sample tray ensures unattended operation and method reproducibility across multi-sample batches.
• Turbomolecular vacuum pump system maintains optimal operating pressure (<1×10⁻⁵ Torr) for stable ion transmission and extended filament life.
• Single quadrupole architecture with unit-mass resolution (1000–2000 FWHM at m/z 502) optimized for targeted quantitation using selected ion monitoring (SIM) and full-scan acquisition.
• ChemStation software (v.E.02.02 or later) provides validated instrument control, data acquisition, spectral library searching (NIST/EPA/NIH), and report generation compliant with GLP documentation requirements.
• Full hardware diagnostics, leak-check routines, and autotune protocols are embedded within the firmware to support routine maintenance and audit readiness.

Sample Compatibility & Compliance

This GC-MS system accommodates standard 1/4″ or 1/8″ capillary columns (e.g., DB-5ms, HP-5MS, VF-WAXms) and supports common injection techniques including split, splitless, on-column, and PTV. It is routinely applied to EPA Method 8270D (semivolatiles), ASTM D7214 (diesel fuel aromatics), USP (residual solvents), and ISO 17025-accredited laboratories performing pesticide residue testing. All refurbished units undergo verification per Agilent’s Factory Acceptance Test (FAT) protocol, and system suitability tests (SST) confirm compliance with ICH Q2(R2) guidelines for method validation parameters including specificity, linearity, LOD/LOQ, and precision.

Software & Data Management

Controlled via Agilent ChemStation, the system supports 21 CFR Part 11-compliant user access levels, electronic signatures, and full audit trail functionality—including timestamped records of method changes, calibration events, and raw data modifications. Raw data (.D files) are stored in vendor-native format with embedded metadata (instrument configuration, tune parameters, acquisition timestamps). Export options include .CSV, .TXT, and .CDF for integration into LIMS environments. SpectraLab provides post-installation software configuration assistance and optional IQ/OQ documentation packages aligned with GMP laboratory implementation standards.

Applications

• Environmental analysis: PAHs, PCBs, chlorinated pesticides, phthalates, and emerging contaminants in soil, water, and air samples.
• Food and beverage testing: Mycotoxins, flavor compounds, packaging migrants, and adulterants in raw materials and finished products.
• Pharmaceutical QC: Residual solvents, extractables/leachables, and degradation products per ICH Q3C and Q5C guidelines.
• Forensic toxicology: Screening and confirmation of drugs of abuse, metabolites, and novel psychoactive substances (NPS) in biological matrices.
• Materials science: Volatile organic emissions (VOCs) from polymers, adhesives, and composites per ASTM D6886 and ISO 16000-6.
