The Agilent G1888 Network Headspace Sampler

GMI offers fully refurbished to specification Agilent model G1888 network headspace autosamplers and currently has stock. The are Re-Certified to specification, and ship with a full warranty.  Installations are available upon request.

Headspace sampling allows you to introduce volatile compounds automatically, from virtually any sample matrix, directly into a GC or GC/MS. The Agilent G1888 Network Headspace Sampler features an inert sample to minimize analyte degradation or loss. Its high sample capacity and increased sensitivity provide excellent performance over a wide range of analyses.


  • 70-sample tray and 12 positions in the heating oven allow unattended overnight operation.
  • Automated overlapping for maximum sample throughput in the minimum amount of time.
  • Coupling with an inert 7890A or 6890N Volatiles Interface achieves system inertness.
  • Controlled temperature range makes it possible to analyze semi-volatiles at temperatures over 200 degrees C, as well as traditional applications for low boiling point analytes.
  • Heated zones can be turned off, which allows analyses at ambient conditions for biological or extremely thermally sensitive analytes.
  • Multi-puncture extraction with up to 100 extractions per vial is possible.
  • A 'concentration mode' of MHE allows multiple extractions from a vial to be made, followed by the start of the GC run after the last extraction.
  • Includes several convenient testing and troubleshooting features, including a set of four pre-stored chemical test methods, a semi-automated leak test, and a detailed power-on self-test.
  • Instrument control is integrated with drop-down menus for ease of method setup. The existing sequence table is used to set up analyses, maintaining optimized sample overlap and constant heating time.
  • An event log function tracks every headspace sampler operation and reports any temperature and pressure deviation compared to the set point in compliance with 21 CFR Part 11
  • Built-in key pad control enables COMPATIBILITY WITH ALL GCs
