Comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry GC×GC–TOFMS has arguably made possible the largest increase in gas chromatograph performance since the innovation of the wall-coated open tubular (WCOT) capillary analytical column in 1979. As with the adoption of capillary columns, taking ...

One- and two-dimensional gas chromatography coupled with mass spectrometry provides an enormous amount of quantitative data describing the chemical composition of complex samples. Besides quantification and identification of analytes, common analysis goals include classifying samples or predicting sample properties based upon ...
