Known for reliability, productivity and longevity, the Agilent GC has a well-earned reputation as a workhorse in the lab. This Agilent 7890A Gas Chromatograph (GC), expertly refurbished by GenTech Scientific, offers everything you need to take your lab to the next level of GC performance.

Features like faster oven cool down and back flushing allow you to get more done in less time, at a lower cost per sample. 5th-generation Electronic Pneumatics Control (EPC) and digital electronics set a new benchmark for pressure set-point and retention time locking precision (0.001 psi) and help make the 7890A one of the most dependable GCs ever. Agilent’s proprietary breakthrough Capillary Flow Technology provides durable and leak-free, in-oven capillary connections. Because the Agilent 7890A system is built upon proven 6890 GC inlets, detectors and GC oven, you can transfer methods to the 7890A GC with complete confidence.

Inlets and detectors and accessories expand the system configuration possibilities. System capabilities support, simultaneously: Two inlets, three detectors (third detector as ECD or TCD) and four detector signals.
