本文利用微电子机械系统(MEMS)技术制作了微气相色谱柱。设计了开管式和半填充式两种塔型。通过比较不同的结构，通过在通道中嵌入方形柱子形成半填充柱，提高了柱的效率。结果表明，半填充柱的柱效可达55MEMS366板/m，首次在实验的基础上报道了 基柱可以达到如此高的塔板数。车牌数量比之前报告的数值高出五倍。此外，使用30米长的安捷伦HP-5商用毛细管柱与使用基于MEMS的半填充柱的结果进行了比较。分析物在两个色谱柱中完全分离。HP-5毛细管柱的柱效为5490片/m，比微细管半填充柱的柱效低10倍。
In this paper, micro gas chromatography columns were fabricated through the micro-electro-mechanical system (MEMS) technique. Two types of columns were designed, namely, open-tube and semi-packed columns. By comparing different structures, column efficiency was improved by embedding square posts in the channel to form a semi-packed column. The result showed that column efficiency of the semi-packed column reached 55 366 plates per m. This study was the first to report based on experimentation that MEMS-based columns can reach a plate number this high. The plate number was five times higher than the value previously reported. In addition, a 30 m-long Agilent HP-5 commercial capillary column was used to compare the results with findings obtained using a MEMS-based semi-packed column. The analytes were perfectly separated in both columns. The column efficiency of the HP-5 capillary column was 5490 plates per m, which was 10 times lower than that of the micro-fabricated, semi-packed column.
