Product Details
- 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
- Large Valve Oven (LVO) allows for the combination of multiple methods and simplified maintenance
- Multimode inlet (MMI) serves as a programmable temperature vaporizing injector with flexible capabilities
- Agilent Inert Flow Path provides increased sensitivity for active compounds, from injection to detection
- Low Thermal Mass (LTM) modules, up to 4 installed and operating, increase sample throughput with rapid column heating and cooling
Improve Your Gas Chromatography with Backflush
Capillary Flow Technology enables flexible implementation of backflush on Agilent GCs for higher throughput, less maintenance, fewer recalibrations, longer column life, better results, and lower costs.
Learn MoreHelium Conservation Module
A helium conservation module for 8890, 8860, or 7890 GC systems can drastically reduce your consumption of helium carrier gas and the associated cost, especially when used with Gas Saver. It can be programmed to switch to a different gas (typically nitrogen) when your GC is idle. The module is compatible with any inlet, backflush, and dual simultaneous injections.
Learn MoreMultidimensional Gas Chromatography
Multidimensional chromatography introduces a second column with a different stationary phase into the flow path. Complex samples often have coeluting compounds so adding the selectivity of an additional column through heart cutting or GC x GC increases the GC resolving power and provides a solution to the problem of overlapping peaks.
Learn MoreRetention Time Locking (RTL)
Retention time locking (RTL) enables the retention times on one Agilent GC or GC/MSD system to be matched exactly on another like system using the same nominal column.
