In this paper, we compare the current separation power of comprehensive two-dimensional gas chromatography (GCxGC) with the potential separation power of GC-mass spectrometry (GC-MS) systems. Using simulated data, we may envisage a GC-MS contour plot, that can be compared with a GCxGC chromatogram. Real examples are used to demonstrate the current potential of the two techniques in the field of hydrocarbon analysis. As a separation technique for complex hydrocarbon mixtures, GCxGC is currently about as powerful as GC-MS is potentially powerful. GC-MS has not reached its potential separation power in this area, because a universal, soft ionization method does not exist. The greatest advantage of GCxGC is, however, its potential for quantitative analysis. Because flame-ionisation detection can be used, quantitative analysis by GCxGC is much more robust, reliable and reproducible.
在本文中，我们将全二维气相色谱（GCxGC）的当前分离能力与气相色谱 - 质谱联用（GC - MS）系统的潜在分离能力进行比较。通过模拟数据，我们可以设想一个GC - MS等高线图，它可以与GCxGC色谱图进行比较。使用实际示例来展示这两种技术在烃类分析领域的当前潜力。作为一种用于复杂烃类混合物的分离技术，GCxGC目前的分离能力与GC - MS的潜在分离能力相当。GC - MS在该领域尚未达到其潜在的分离能力，因为不存在通用的软电离方法。然而，GCxGC的最大优势在于其定量分析的潜力。由于可以使用火焰离子化检测，GCxGC进行的定量分析更加稳健、可靠且可重复。
