Agilent 6890N Gas Chromatograph with 5975 Inert Mass Selective Detector (G3171A) and 7683 Liquid Autosampler, robust GC-MS system for environmental testing, food safety analysis, pharmaceutical research, forensic toxicology, and industrial chemical applications.

Key Features

  • Inert Ion Source Design
    The 5975 Inert MSD features an inert ion source for improved response, especially to active compounds and late-eluting analytes.

  • Extended Mass Range & High Sensitivity
    Runs up to m/z 1050, with enhanced sensitivity (e.g., EI scan 182:1 S/N at 1 pg OFN; CI scan up to 500:1).

  • Standard Turbo Pump, Robust Vacuum System
    Equipped with the standard turbomolecular pump for stable operation; straightforward maintenance with a user-friendly design.

  • AutoCI™ Capability
    Enables fully automated switching between EI and CI modes within a sequence, streamlining method setup and reducing manual intervention.

  • Modular and Service-Friendly Construction
    Features such as quick-swap interfaces and a functional front window allow easier filament and column access, reducing downtime.

  • Precision Sampling & Minimal Carryover
    The 7683 ALS provides injection volumes from 0.1 µL to 50 µL, variable sampling depths, and dual solvent washes to virtually eliminate carryover.

  • High Throughput and Flexibility
    Dual simultaneous injection, priority sampling, and next-sample overlap enhance throughput—ideal for busy labs.


Applications

  • Environmental Analysis: Pesticides, pollutants, and emerging contaminants

  • Forensics & Toxicology: Trace-level compound identification

  • Pharmaceuticals & Metabolomics: Profile drug compounds and metabolites with high sensitivity

  • Food & Flavor Testing: Detect and quantify volatiles, residues, and additives

  • Materials & Polymers: Characterize VOCs and organic modifiers
