GC012 Advantages of gas chromatography - Part 2
GC provides
fast separations, and current commercial instrumentation permit analysis to be performed
in seconds. A technique called comprehensive two-dimensional GC (GCxGC) has been
developed recently, which implies the injection of the eluent from a
traditional separation into a very short column, a second column. The second analysis
requires just a few seconds to be completed. The result obtained is a GCxGC
contour plot where we have the second dimension, represented in a y-axis.
