7890A GC System

Adding an exciting new chapter to a 40-year history of GC leadership, Agilent’s 7890A GC gives you everything you need to take your lab to the next level of GC and GC/MS performance, including advanced separation capabilities, powerful new productivity enhancements and real-time self-monitoring instrument intelligence. Faster oven cool-down and backflushing let you 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 setpoint and retention time locking precision (0.001 psi) and help make the 7890A our most dependable GC ever.

    Fast Refinery Gas Analyzer
    Attributes

    This model was added by: LabWrenchSiteAdmin

    Edit Model

    Additional Specifications An exact and fast analysis of refinery gas is essential for optimizing refinery processes and controlling product quality. A 7890A GC configured for simultaneous operation of three parallel channels provides a complete refinery gas analysis in six minutes. The system conforms to ASTM D1945, D1946, and UOP 539 standard methods.
    Greenhouse Gases Analyzer
    Attributes

    This model was added by: LabWrenchSiteAdmin

    Edit Model

    Additional Specifications Carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) are considered the main greenhouse gases in the Earth’s atmosphere. Continuous measurement of these gases provides meaningful information to track greenhouse gases emission trends and helps in the fight against climate change. Two Greenhouse Gases Analyzers based on the Agilent 7890A GC have been developed to meet the different requirements for simultaneous analysis of CH4, CO2, and N2O in air samples. Both systems can easily be expanded to determine sulfur hexafluoride (SF6) and demonstrate high sensitivity with excellent repeatability.
    Biodiesel Analyzer
    Attributes
