Since the comprehensive two-dimensional gas chromatography (GC × GC) technique is becoming more and more available for scientists as well as for laboratories performing routine analyses, the most successful field of applications are petrochemical, food and essential oil analysis. However, this technique coupled with TOF-MS (P.1, l. 27) could be even more successfully used in the field of metabolomics. The review presents briefly the concept of comprehensive 2D GC and the principles of the technique. Certain specific applications are discussed to show the usefulness of GC × GC combined with different detectors for determination of compounds not always easy to measure with other techniques.

全面气相色谱：食品和代谢组学应用。

由于全面的二维气相色谱（GC×GC）技术对科学家以及进行常规分析的实验室越来越可用，因此最成功的应用领域是石油化学，食品和精油分析。但是，这种与TOF-MS结合的技术（第1页，第27页）甚至可以更成功地用于代谢组学领域。这篇综述简要介绍了综合二维气相色谱的概念以及该技术的原理。讨论了某些特定的应用程序，以显示GC×GC与不同的检测器组合用于确定并非总是易于通过其他技术测量的化合物的有用性。
