There is revived interest in the development and implementation of methods of faster GC. The paper summarises the advantages of faster GC analysis, general approaches to faster GC method development and practical aspects of fast gas chromatography with the utilisation of open tubular capillary columns with the stress on trace analysis. There are a number of ways to take the advantage of the improved speed of analysis by faster GC. Numerous options exist for pushing the speed of capillary gas chromatography (CGC) analysis. The scope of this paper is also to give an overview of the present state of faster GC instrumentation which is already available for trace analysis. The practicality of fast CGC is a function of sample preparation and the matrix interferences and how they affect the resultant resolution that may be achieved. Researchers have demonstrated the applicability of fast GC to trace and ultratrace analysis of volatile and semivolatile compounds also with narrow bore columns and difficult sample matrices (such as food, and soil extract). The main development of faster GC methods has been observed in the field of environmental analysis. Practical applications are presented. Both optimised sample preparation and experimental conditions for faster GC are the future perspective of trace analysis.
人们对更快的气相色谱法的开发和应用重新产生了兴趣。本文总结了更快的气相色谱分析的优势、更快的气相色谱方法开发的一般方法以及利用开口管毛细管柱进行快速气相色谱分析的实际方面，重点是痕量分析。有多种方法可以利用更快的气相色谱提高分析速度的优势。推动毛细管气相色谱（CGC）分析速度的选择众多。本文的范围还包括概述已可用于痕量分析的更快的气相色谱仪器的现状。快速CGC的实用性取决于样品制备、基质干扰以及它们如何影响可能实现的最终分离度。研究人员已经证明了快速GC在挥发性和半挥发性化合物的痕量和超痕量分析中的适用性，包括使用窄口径柱和复杂样品基质（如食品和土壤提取物）的情况。更快的气相色谱方法的主要发展出现在环境分析领域。文中介绍了实际应用。优化的样品制备和更快的气相色谱的实验条件都是痕量分析的未来发展方向。
