Refurbished Agilent Technologies 7890

Refurbished Agilent 7890 Gas Chromatographs


Agilent 7890 Series Gas Chromatograph

After 40 years in the making, the Agilent 7890 GC replaced the 6890N offering unsurpassed retention time reproducibility and real-time self-monitoring instrument intelligence. Plus, of course, the same reliability that we have come to know from Agilent Technologies. Contact us to request a quote for a customer configured Agilent 7890 GC system.


Agilent 7890 Mainframes

The 7890 GC's combination of precise pneumatic and temperature control leads to extremely precise retention time reproducibility, which is the basis for all chromatographic measurement.

7890A GC - The Agilent 7890A is a state-of-the-art gas chromatograph that provides superior performance for all applications.

7890B GC - Has enhanced firmware with built-in capabilities to monitor system resources (counters, electronic logs and diagnostics)


Agilent 7890 Detector Options

  • FID - Flame Ionization Detector - Is the most commonly used detector in gas chromatography because of its dependability and universal ease of use. It detects practically any organic compounds while generating little to zero signal for common carrier gases.
  • uECD - micro Electron Capture Detector - produces trace-level detection of halogenated organic compounds and aromatic pollutants
  • TCD - Thermal Conductivity Detector - used for the GC analysis of permanent gases, light hydrocarbons, and compounds that do not respond well to a flame ionization detector (FID)
  • PID - Photo Ionization Detector - selectively responds to aromatic and olefinic hydrocarbons in the presence of alkanes and other saturated hydrocarbons
  • FPD - Flame Photometric Detector - used for sulfur and phosphorus
  • NPD - Nitrogen Phosphorus Detector - specific to nitrogen or phosphorus containing compounds
  • PDD - Pulsed Discharge Detector - the PDD is a selective detector for monitoring high electron affinity compounds such as freons, chlorinated pesticides, and other halogen compounds
  • MSD - Mass Selective Detector - measures the mass-to-charge ratio (m/z) of one or more molecules present in a sample. These measurements can be used to calculate the exact molecular weight of the sample components
  • Triple Quadrupole TQ Mass Spec - a mass detection technology that can be adapted to a wide range of applications
  • Non Destructive Detectors such as TCD and PID can also be configured in tandem (or in series) with others to provide data from both detectors with a single injection

Agilent Technologies 7890 GC Inlet Options

  • Agilent 7890 Split/Splitless Inlet - Most widely-used inlet for gas chromatography
  • Agilent 7890 Cool On-Column Inlet - Ideal for thermally labile or unstable compounds
  • Agilent 7890 Purged Packed Inlet - Direct injection onto packed and wide-bore capillary columns
  • Agilent 7890 PTV Inlet - Programmable temperature vaporizer combines the benefits of split/splitless and cool on-column
  • Agilent 7890 Volatiles Interface - Introduce gas samples into a GC from an external device
