Agilent 7890B GC

When operating budgets are a concern, the 7890B Gas Chromatography System offers innovations that demonstrate real value. The 7890B GC delivers performance not possible in previous GC systems; performance and modularity of GC and MS detection systems provide increased sensitivity. Additional innovations include: precise carrier and detector gas control, early maintenance feedback, and out-of-the-box application Analyzers.

Features

  • Retention Time Locking (RTL) maintains exact retention times from injection to injection, column to column, instrument to instrument, and lab to lab
  • Capillary Flow Technology (CFT) provides unique instrument capabilities, such as multi-dimension gas chromatography (GC-GC/Deans Switch), comprehensive two-dimension gas chromatography (GCxGC) with flow modulation, and backflush at the beginning, middle, or end of the analytical column
  • Single filament TCD that does not require a separate reference gas, does not require manual potentiometer adjustment, and provides a stable baseline with a minimal amount of signal drift
  • Auto-ranging FID provides the ability to detect and quantitate from parts per billion (ppb) to parts per thousand in a single injection
  • Integrated SCD/NCD (sulfur or nitrogen chemiluminescence detector) provides low ppb detection, equi-molar response, and quantitation for sulfur or nitrogen contaminants without quenching from matrix
  • Carrier Gas Options: Helium Conservation Module, Hydrogen Sensors and Alternate Carrier Gas Solutions dramatically reduce the amount of helium used to offer flexibility in your laboratory
  • Large Valve Oven (LVO) allows for the combination of multiple methods and simplified maintenance
  • Multimode inlet (MMI) serves as a programmable temperature vaporizing injector with flexible capabilities
  • Agilent Inert Flow Path provides increased sensitivity for active compounds, from injection to detection
  • Low Thermal Mass (LTM) modules, up to 4 installed and operating, increase sample throughput with rapid column heating and cooling
