Agilent 7890A GC System (G3440A)  High-performance gas chromatograph with EPC, dual inlets and detectors, and versatile applications in environmental, pharmaceutical, petrochemical, and food testing

Key Features:

  • Next-generation platform built on the legacy of the 6890 GC, offering enhanced performance, reliability, and automation.

  • Advanced Electronic Pneumatic Control (EPC): Delivers superior pressure/flow precision, ensuring highly reproducible retention times and consistent performance.

  • Rapid oven heating and cooling (ambient +4 °C to 450 °C) for shorter cycle times and high-throughput labs.

  • Dual-channel capability: Supports up to two inlets and two detectors simultaneously for flexible workflows.

  • Flexible inlet options: Split/Splitless, Multimode Inlet (MMI/PTV), Cool On-Column, Packed.

  • Extensive detector portfolio: Flame Ionization Detector (FID), Electron Capture Detector (ECD), Nitrogen Phosphorus Detector (NPD), Thermal Conductivity Detector (TCD), Flame Photometric Detector (FPD), Pulsed FPD (PFPD), and coupling with Agilent MSD systems (5975/5977).

  • Time-Programmed Selectivity (detector operation optimization with changing conditions during analysis).

  • Configurable backflush technology reduces matrix interference, improves column life, and decreases cycle time.

  • Robust column oven with >20 programmable ramps, allowing complex temperature programs for difficult separations.

  • Compatible with Agilent 7693 and 7683B Autosamplers, with vial capacities up to 150 for unattended operation.

  • Integrated LAN connectivity for easier system control and remote access.

  • ChemStation and OpenLab CDS compatibility, providing regulatory-ready software with 21 CFR Part 11 compliance.

  • High reliability and long instrument lifespan, designed to run continuously in demanding QC and research labs.

  • Upgradeable to full GC/MS workflows, making it a flexible platform for both routine and advanced analyses.


Applications:

  • Environmental Testing: VOCs, SVOCs, pesticides, herbicides, and persistent organic pollutants (POPs) in water, soil, and air.

  • Petrochemical & Energy: Detailed hydrocarbon analysis (DHA), simulated distillation (SIMDIS), natural gas composition, sulfur compounds.

  • Food & Beverage: Flavor/fragrance analysis, food safety testing (pesticide residues, contaminants), packaging extractables and leachables.

  • Pharmaceutical Industry: Residual solvent testing (ICH Q3C), raw material purity, QC of active pharmaceutical ingredients (APIs) and excipients.

  • Forensic Science: Toxicological screening, drug profiling, arson investigations (fire debris, accelerant residues).

  • Clinical & Biomedical: Fatty acid methyl ester (FAME) profiling, blood alcohol content (BAC), metabolic biomarker screening.

  • Industrial & Chemical Manufacturing: Specialty chemical QC, monomers, polymers, and process gas analysis.

  • Academic & Government Research: Advanced GC method development, teaching, and multi-detector research studies.
