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
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
