The Agilent 7890A Gas Chromatograph is a state-of-the-art gas chromatograph with excellent performance for any application. The outstanding performance is guaranteed by advanced Electronic Pneumatic Control (EPC) modules and extremely precise control of the GC oven temperature. Each EPC unit is optimized for its intended use and equipped with specific injector and detector. The temperature control of the 7890A GC oven allows for fast and precise gradients. The overall thermal performance ensures optimal chromatography with peak symmetry, retention time repeatability, and retention index accuracy. Agilent's Capillary Flow Technology provides a new dimension to chromatography, ensuring reliable and leak-free capillary connections in the oven that can withstand repeated cycles. The 7890A GC features enhanced firmware to expand the capabilities of the innovative capillary flow modules and advanced software to simplify backflush setup and operation. In addition to facilitating the analysis of complex matrices, it offers increased flexibility and reliability.
The Agilent 7890A Network Gas Chromatograph is a high-performance instrument designed for various analytical applications. It features advanced Electronic Pneumatic Control (EPC) modules and precise oven temperature control to ensure excellent reproducibility and peak symmetry. The system supports up to two injectors and three detectors, with the third detector capable of being a TCD. This manual is written in Italian.
