Key Features

• 7890A Gas Chromatograph

  • Advanced Electronic Pneumatic Control (EPC) with precise temperature programming up to 450 °C (with optional cryogenic cooling down to –80 °C using LN₂).

  • Supports fast ramp rates, up to 120 °C/min, multi-step ramps, and detailed run-time logging.

  • Networked control and local interface for leak testing, maintenance, and diagnostics.

• 5975C VL TAD Mass Selective Detector (Triple-Axis Detector)

  • Low-noise Triple-Axis Detector (TAD) for enhanced sensitivity and reduced background noise.

  • Standard Electron Impact (EI) ionization, with optional Positive/Negative Chemical Ionization (PCI/NCI).

  • Turbo pump configuration available for superior scan speeds and signal-to-noise.

  • Compact footprint: approx. 88 cm (W) × 56 cm (D) × 50 cm (H); weight 81–96 kg depending on configuration.

• 7693 Autosampler

  • Fully automated tray-based liquid injection system.

  • Improves reproducibility and throughput while minimizing manual handling errors.

  • Integrates with ChemStation software for full automation.

Applications

• Environmental testing—trace VOCs, pollutants in water, air, and soil

• Food safety—pesticide residues, flavor analysis, and contaminant detection

• Forensics—analysis of drugs, toxins, and biological markers

• Pharmaceuticals—residual solvents, impurities, and QC monitoring

• Industrial R&D and QA—both targeted quantitation and screening
