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 at GenTech Scientific, offers everything you need to take your lab to the next level of GC performance.

Features like faster heating and cooling allows for shorter analysis times and increased throughput – 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. The split splitless injector allows for versatile sample introduction, with split mode for trace analysis and splitless mode for higher sensitivity. 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.

The Nitrogen Phosphorous Detector (NPD) makes it possible to analyze organic compounds containing nitrogen or phosphorous.

Robust and reliable, with proven precision and sensitivity, this Agilent 7890A GC with NPD offers next level performance. This 7890A GC comes refurbished and tested from GenTech Scientific. Request a quote today!
