7820A GC System from Agilent Technologies

The 7820A Gas Chromatography system is an affordable, high-quality GC instrument for small to medium-sized labs concerned with routine analyses. This system provides modern capabilities for a wide range of application areas, including a full range of detector options, such as Agilent’s single quadrupole mass spectrometer. Inlet devices for the 7820A GC allow analysis of liquid, gas, volatile, and solid samples.


  • Retention Time Locking (RTL) maintains exact retention times from injection to injection, column to column, instrument to instrument, and lab to lab
  • Electronic Pneumatics Regulation (EPR) option provides the simplicity of manual operation with high precision digital display of pressure/flow and superior ease-of-use as compared to traditional manual pneumatics systems
  • Great fit for routine MSD applications
  • Single filament TCD that does not require a separate reference gas, does not require manual potentiometer adjustment, and provides a stable baseline without drift
  • Auto-ranging FID provides the ability to detect and quantitate from parts per billion (ppb) to parts per thousand in a single injection
  • Full electronic pneumatic control (EPC) from inlet to detection system
  • Simplified GC front panel keys and display provide sequence information, instrument conditions, and run status, and minimize operating errors
  • Software keyboard and display allows the user to control the system when it connects with an integrator or 3rd-party software
