Objectives and Study Overview

This data sheet presents the design features, performance metrics and operational benefits of the Agilent 8890/5977C GC/MSD system. It highlights the system’s detection limits, signal-to-noise performance, maintenance features and long-term support promise to guide users in selecting a high-throughput, high-sensitivity platform.

Methodology and Instrumentation Used

• Gas Chromatograph: Agilent 8890, 8860 or Intuvo 9000 GC with flexible inlet options (split/splitless, multimode, on-column) and autosamplers (liquid, headspace, purge-trap).
• Mass Spectrometer: 5977C quadrupole MSD featuring five ion source configurations – stainless steel, Inert Plus, extractor, HydroInert (H₂ carrier) and High-Efficiency Source (HES).
• Ionization Modes: Standard electron ionization (EI); optional positive/negative chemical ionization (PCI/NCI) using dedicated reagent gas control.
• Performance Validation: Installation checkout of instrument detection limit (IDL) and signal-to-noise (S/N) using consecutive injections of octafluoronaphthalene (OFN) or benzophenone standards.

Main Results and Discussion

• Instrument Detection Limits: Achieves as low as 1.5 fg (HES, He carrier) and 50 fg (HydroInert, H₂ carrier), validating industry-leading sensitivity.
• Signal-to-Noise Ratios: Exceeds 2000:1 in EI scan mode with Helium and up to 5000:1 with EI/CI source configurations, ensuring clear peak detection at trace concentrations.
• Mass Performance: Unit mass resolution over 0.6–1091 u range; mass accuracy of ±0.005 u and spectral accuracy >99% for OFN standard injections.
• Scan Speeds: Up to 20,000 u/sec with HES and extractor sources, balancing high throughput with sensitivity retention.
• Maintenance Features: Removable source and detector modules for rapid servicing, automated JetClean source cleaning, and Early Maintenance Feedback (EMF) to predict service intervals.
• Data System: Agilent MassHunter or OpenLab CDS offering acquisition, quantitation, compliance tools (21 CFR Part 11), and integrated spectral libraries.

Benefits and Practical Applications of the Method

• Enables trace-level quantitation in environmental, food safety, forensic and pharmaceutical analyses.
• Versatile source and ionization choices support targeted SIM workflows and comprehensive scan-based investigations.
• Robust source design and automated cleaning minimize downtime in high-volume laboratories.
