Gas chromatography-mass spectroscopy (GC-MS) is actually two techniques that are combined to form a single method of analyzing mixtures of chemicals. If you are new to this technique, please read our tutorial first.

The Agilent 6890 GC-MS was donated by FBI in Summer, 2009. This Agilent Gas Chromatograph was designed to replace the older model HP5890. This newer GC system delivers high levels of performance and features an electronic pneumatics control of all flows and gas pressures. Agilent 6890 has on-board sensors that automatically compensate for ambient temperature changes and barometric pressure differences to routinely achieve and produce more accurate and reproducible results.

The Agilent 6890 produces excellent performance for many applications. Overall thermal performance provides optimal chromatography including retention time repeatability, peak symmetry, and retention index accuracy, while allowing for fast GC results. The accurate temperature together with its precise pneumatic control leads to outstanding retention time repeatability, the basis for all chromatographic measurement.

HP 5973 MSD Features:

  • Mass range - between 1.6 and 800 amu in 0.1 amu steps.
  • Scan speed - max of 5200 amu/sec with 0.1 amu resolution.
  • Sensitivity - Typical performance for 1pg of Octafluoronaphthalene yields a signal to noise ratio of better than 20:1 at scan mass range 50-300 amu.
  • SIM mode - monitors up to 30 masses at a time. Up to 50 groups of 30 masses.


This 6890 GC- 5973 MSD is located at the Prince William Campus in SRIF Lab 221of Discovery Hall Building.
