摘要： A GC-IMS system is disclosed in embodiments of the present invention. The system comprises a sample transfer device. The sample transfer device connects the gas chromatograph to the reaction region and, the sample from the gas chromatograph is transferred to the reaction region by the sample transfer device directly, instead of not through the ionization region. With the GC-IMS system, generation of sample molecular ion fragments can be avoided so that the spectrum is brevity and is easily identified; moreover, the application field of the GC-IMS system is extended to a range of analysis of organic macromolecule samples which have a high polarity, are difficult to volatilize, and are thermally instable. On the other hand, the GC-IMS system overcomes the defect of ion destruction due to neutralization reaction among positive and negative ions so as to evade the detection.
摘要翻译： 在本发明的实施例中公开了一种GC-IMS系统。 该系统包括样品转移装置。 样品转移装置将气相色谱仪连接到反应区域，气相色谱仪的样品直接通过样品转移装置转移到反应区域，而不是通过电离区域。 使用GC-IMS系统，可以避免产生样品分子离子片段，使得光谱简洁易于识别; 此外，GC-IMS系统的应用领域扩展到具有高极性，难以挥发和热不稳定的有机大分子样品的一系列分析。 另一方面，GC-IMS系统克服了由于正离子和负离子之间的中和反应引起的离子破坏的缺陷，以避免检测。
