Agilent 6890 GC with Surface Measurement System (Inverse Gas Chromatograph, iGC)

Chromatographic Performance

-Retention time repeatability<0.008% or <0.0008 min
-Area repeatability <1%RSD

-The Agilent 6890N is a state-of-the-art gas chromatograph that provides superior performance for all applications. Key to its performance is the use of advanced electronic pneumatic control (EPC) modules and high performance temperature control.
-Each EPC unit is optimized for its intended use
with a specific inlet and detector option.

The Agilent 6890 GC with Surface Measurement System is the world’s first commercial inverse gas chromatograph. The Surface Measurement System (SMS) flow control technology provides the state-of-the-art in humidity control together with unrivalled accuracy and reproducibility. The standard instrument configuration comes with a thermal conductivity detector (TCD) and a flame ionization detector (FID) : this combination allows differentiation between moisture and organic solvent elutants. Further detectors (e.g. Mass Spectrometer) may be added according to customer requirements.

Standard methods for surface energy, heat of sorption, phase transition, sorption isotherms and frontal methods.
