Agilent 7890B Gas Chromatography System

The Agilent 7890B GC is the industry-standard gas chromatograph, trusted in thousands of laboratories worldwide. Designed for continuous operation in intensive analytical modes, the instrument combines a proven design with improved performance. The column thermostat design ensures uniform heating throughout the chamber, which is critical when working with long capillary columns and complex temperature programs. Electronic Pressure Control (EPC) is integrated into the instrument, providing up to 13 independent channels, allowing precise flow control in injectors, detectors, and auxiliary pneumatic components. The instrument supports the simultaneous installation of two injectors (split/splitless, pulsating split/splitless, multimode injector, and cold injector with programmable temperature) and three detectors (flame ionization, thermal conductivity, electron capture, flame photometry, nitrogen and phosphorus flame ionization). This configuration flexibility allows for a wide range of analytical applications, from air pollution monitoring to quality control of petroleum products and pharmaceutical substances. A built-in diagnostic system monitors the life of consumable components and promptly notifies the operator of the need for preventive maintenance. The instrument is compatible with all Agilent mass-selective detectors, enabling the transition from simple chromatography to GC/MS analysis without replacing the base unit.
