Comprehensive two-dimensional gas chromatography (GC×GC) provides very high resolution power and unmatched peak capacity. In addition, the 2D chromatograms are highly structured and allow linking the compound position in the 2D space to properties such as volatility and polarity. As a consequence, 2D patterns are very informative and specific and can be exploited for comparison and classification of complex samples. Here we show the use HS-SPME-GC×GC-QTOF for the fingerprinting of Earl Grey tea leaves from different commercial brands.
