Product Details
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-dimensional 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
