Choosing a Gas Chromatograph in a Technologically Advanced Market

WHITE PAPER: TWP010

Angela CantrellTEVET

Differentiation of compounds via gas chromatography is one of the most widely employed analytical techniques used throughout research and industry.1 Choosing a gas chromatograph in a market saturated with information and technology can be a difficult task, given the wide reach of marketing.

In today’s era of automated gas chromatography, only one product stands out as the clear leader in the field. Agilent Technologies’ 7890B Gas Chromatograph provides consistent and reliable results with industry-leading speed and functionality while overcoming a number of challenges posed by the chromatography process.

APPLICATION AND FEATURES

The Agilent 7890B Gas Chromatograph features Retention Time Locking (RTL), which allows for unparalleled reproducibility, regardless of user, location, or material variability.(Fig. 1) Agilent’s proprietary Capillary Flow Technology (CFT) creates leak-free column connections that withstand the extreme temperatures of a modern GC oven. The backflush prevents carryover retention time shifts and source contamination. (Fig. 2)

The 7890B also applies single filament TCD technology which contributes to little signal drift. The auto-ranging FID and integrated SCD/NCD (sulfur or nitrogen chemiluminescence detector) provides the capacity to detect and quantitate from parts-per-billion to parts-per-thousand in a single injection.2 Time-saving features such at the Large Valve Oven (LVO) and Low Thermal Mass (LTM) allow users to combine methods and increase throughput with rapid heating and cooling. The Multi-mode Inlet (MMI) acts as an adjustable temperature vaporizing injector, allowing for cold split-less and large volume injections. (Fig. 3) Agilent’s Inert Flow Path ensures unmatched sensitivity for semi-volatile compounds throughout the process. (Fig. 4) The unit also utilizes eco-friendly features including alternative carrier gases, sleep/wake modes, and helium conservation, which save valuable resources.
