本文介绍了为综合二维气相色谱 (GC x GC) 开发的阀门切换调制系统的新设计。该系统基于差动流量，与文献中早期报道的不同。它具有多种优点，并且由廉价的市售部件构成，可以轻松安装在大多数气相色谱仪上。操作简单且稳定，无需外部冷却剂。这种新设计允许在任何能够支持传统 GC 的实验室环境中进行 GC x GC 分析，并且不会产生额外的耗材成本。该系统非常灵活，允许使用多种固定相组合。该系统已成功通过完整材料传输测试，适用于定量分析。该系统的灵活性通过多种测试混合物得到证明，显示了其在石油、生物化学和环境研究中的广泛应用。 (C) 2008 Elsevier B.V. 保留所有权利。
This paper describes a new design for a valve switching modulation system developed for comprehensive two-dimensional gas chromatography (GC x GC). This system is based on the differential flow and is different from the earlier reported in the literature. It has several advantages and constructed of inexpensive, commercially available parts that are easily installed on most gas chromatographs. Operation is easy and robust and requires no external coolants. This new design allows GC x GC analysis to be conducted in any laboratory environment capable of supporting conventional GC and imposes no additional consumable costs. The system is flexible and permits the use of a wide range of stationary phase combinations. The system has been successfully tested for complete material transfer and is suitable for quantitative analysis. The flexibility of this system is demonstrated using several test mixtures that show its extended application in petroleum, biochemistry, and environmental studies. (C) 2008 Elsevier B.V.
