Gas chromatograph 7890B GC

laboratoryFIDTCD

The 7890B GC System has been discontinued but is still being supported by Agilent and accessories can still be purchased. Units may be available through the Agilent Refurbished Instruments program. For our latest gas chromatography systems, which provide advanced capabilities and benefits, please see the 8890 GC, Intuvo 9000 GC, and 8860 GC. Features Retention Time Locking (RTL) maintains exact retention times from injection to injection, column to column, instrument to instrument, and lab to lab Capillary Flow Technology (CFT) provides unique instrument capabilities, such as multi-dimension gas chromatography (GC-GC/Deans Switch), comprehensive two-dimension gas chromatography (GCxGC) with flow modulation, and backflush at the beginning, middle, or end of the analytical column Single filament TCD that does not require a separate reference gas, does not require manual potentiometer adjustment, and provides a stable baseline with a minimal amount of signal drift Auto-ranging FID provides the ability to detect and quantitate from parts per billion (ppb) to parts per thousand in a single injection Integrated SCD/NCD (sulfur or nitrogen chemiluminescence detector) provides low ppb detection, equi-molar response, and quantitation for sulfur or nitrogen contaminants without quenching from matrix Helium conservation module and alternative carrier gas solutions dramatically reduce the amount of helium used to offer flexibility and cost savings for your laboratory Optional Hydrogen Sensor Module Series 2 detects hydrogen leaks early and shuts off gas flows, continuously monitors status using built-in intelligent diagnostics, and requires calibration only every six months
