A recent trend in the development of analytical methodologies is the integration of the sample preparation step directly with the chromatographic system. In integrated on-line systems, extraction, clean-up, separation and detection are connected with each other and the whole analytical procedure takes place in a closed, usually automated system. In this review, a critical overview of the principles and benefits of on-line coupling of extraction with gas chromatography is presented. Techniques suitable for the extraction and analysis of various types of compounds in both solid and liquid samples are presented. The potential of on-line techniques is discussed and illustrated with selected examples.
分析方法发展的一个最新趋势是将样品制备步骤直接与色谱系统相结合。在集成在线系统中，萃取、净化、分离和检测相互连接，整个分析过程在一个封闭的、通常是自动化的系统中进行。在本综述中，对萃取与气相色谱在线联用的原理和优点进行了批判性概述。介绍了适用于固体和液体样品中各类化合物萃取和分析的技术。通过选定的示例讨论并说明了在线技术的潜力。
