The Agilent 7890 A/B is a newer GC model intended to replace the 6890. It possesses improvements such as greater sensitivity, lower noise, and better retention times due to its 5th-generation EPC system. It also allows for the addition of a third detector (TCD). It possesses a multimode inlet that is split/splitless, has temperature ramping, and has large volume injection capabilities. These updates allow for greater utility.

The Agilent 8890 is the newest GC model released to date. It possesses improvements over the 7890 such as the 6th generation EPC. This microchannel-based EPC prevents gas-based contamination of the EPC system. This increases the reliability of the EPC and its associated maintenance costs. It also possesses more advanced and automated diagnostics that monitors the instrument’s health.
