Agilent Capillary Flow Technology's, reliable, leak-free, in-oven design now provides comprehensive multidimensional chromatography, also called GC x GC, offering powerful capabilities for analyzing complex mixtures such as petrochemicals, fragrances and environmental samples. In GC x GC, peak generation can be significantly greater than conventional GC. Compared to a single column separation, GC x GC can improve peak resolution and peak capacity to provide highly detailed sample characterization. Advantages of GC x GC analysis include excellent visualization of sample components, class determination, sample fingerprinting and screening.
