填充柱气相色谱仪在国内使用的数量已相当可观。近年来随着气相色谱技术的发展,毛细管色谱又成为色谱分析中不可缺少的重要手段,但购买新的毛细管色谱仪将带来经费上的负担。把填充柱色谱仪改装成毛细管色谱仪,从经济和实用方面看,无疑都是十分有利的选择,既能节约经费,又能满足色谱分析的需要,因而受到普遍欢迎。为了便于用户改装仪器,我们设计了一套毛细管附件装置,适用于 The number of packed column gas chromatographs used in China has been considerable. In recent years, with the development of gas chromatography technology, capillary chromatography has become an indispensable means of chromatographic analysis, but the purchase of a new capillary chromatography will bring the financial burden. Converting a packed column chromatograph to a capillary chromatograph is undoubtedly a very advantageous option both economically and practically for saving money as well as meeting the needs of chromatographic analysis and is therefore universally welcomed. In order to facilitate the user to modify the instrument, we designed a capillary attachment device, suitable for
