GC x GC is a powerful gas chromatography technique for analyzing complex mixtures such as petrochemicals, fragrances, and environmental samples. Compared to conventional gas chromatography, GC x GC can improve peak resolution and peak capacity to provide highly detailed sample characterization.
Agilent Capillary Flow Technology simplifies comprehensive gas chromatography (GC x GC) by eliminating the need for costly cryogens. This technology is integrated into the Agilent 7890A Gas Chromatograph, making advanced analysis accessible for routine laboratory settings. The system utilizes a proprietary Capillary Flow device interfaced with an auxiliary pneumatic control module to precisely modulate flow and focus analyte bands.
The technology eliminates the need for costly and troublesome cryogens, making the technique more accessible and affordable.
It operates on a simple principle of differential flow modulation rather than relying on rapid heating and cooling cycles.
The instrument provides a fast FID capable of up to 500 Hz for useful data acquisition speeds.
