Abstract

We developed a complete computer-controlled smart 3-dimensional gas chromatography (3-D GC) system with an automation algorithm. This smart 3-D GC architecture enabled independent optimization of and control over each dimension of separation and allowed for much longer separation time for the second- and third-dimensional columns than the conventional comprehensive 3-D GC could normally achieve. Therefore, it can potentially be employed to construct a novel GC system that exploits the multidimensional separation capability to a greater extent. In this Article, we introduced the smart 3-D GC concept, described its operation, and demonstrated its feasibility by separating 22 vapor analytes.

摘要

我们开发了一种完整的计算机控制智能三维气相色谱（3-D GC）系统，具有自动化算法。这种智能 3-D GC 架构允许对每个分离维度进行独立优化和控制，并允许第二维和第三维柱的分离时间比传统的全二维 3-D GC 通常能够达到的时间长得多。因此，它有可能被用于构建一种新型的 GC 系统，以更大程度地利用多维分离能力。在本文中，我们介绍了智能 3-D GC 的概念，描述了它的操作，并通过分离 22 种蒸气分析物证明了它的可行性。
