The Agilent 7890A is a state-of-the-art gas chromatograph that provides superior performance for all applications. Key to its performance is the use of advanced electronic pneumatic control (EPC) modules and high performance GC oven temperature control. The combination of precise pneumatic and temperature control leads to extremely precise retention time reproducibility, which is the basis for all chromatographic measurement. Agilent’s proprietary Capillary Flow Technology provides a new dimension in chromatography with reliable, leak-free, in-oven capillary connections that stand up to repeated GC oven cycling over time. The 7890A GC has enhanced firmware to extend Capillary Flow capabilities and enhanced datasystem software to simplify set-up and operation of backflush. These new tools make it easier to analyze complex matrices and unknowns, and provide gains in productivity and data integrity for routine analyses via 2-dimensional heart cutting, detector splitting, and backflush.
The Agilent 7890A is a network gas chromatograph designed for superior performance in all applications. It utilizes advanced electronic pneumatic control (EPC) modules and high-performance oven temperature control to ensure precise retention time reproducibility and optimal chromatography, including peak symmetry and retention index accuracy.
Key features include Capillary Flow Technology for leak-free connections, support for up to two inlets and three detectors, and full EPC availability for all inlet and detector options. The system supports various inlet types such as split/splitless, multimode, and temperature-programmable cool on-column (PCOC), along with a wide range of oven operating temperatures from ambient +4 °C up to 450 °C.
