Abstract
A device for the continuous monitoring of the volatile and semivolatile organic compounds in air by membrane extraction followed by sorbent concentration and gas chromatographic separation is discussed. The device samples headspace and makes automatic injections followed by rapid separation and quantification. The main components of the system include membrane module, microtrap, and transfer line. A membrane module, microtrap, and fan are mounted in a housing, together constituting a MESI (membrane-extraction sorbent interface) sampling unit. A heated silicosteel capillary column was used as the transfer line, avoiding adsorption and condensation of analytes and performing separation of the analytes prior to detection. The device demonstrated potential for field monitoring of aromatic hydrocarbons, chlorinated compounds, and terpenoids. © 2001 John Wiley & Sons, Inc. Field Analyt Chem Technol 5: 69–74, 2001
基于吸附界面膜萃取和微型气相色谱仪的连续监测装置设计
介绍了一种膜萃取-吸附剂浓缩-气相色谱分离连续监测空气中挥发性和半挥发性有机物的装置。该装置对顶空取样并自动进样，随后进行快速分离和定量。该系统的主要组成部分包括膜模块、微疏水阀和输送管线。膜模块、微捕集器和风扇安装在外壳中，共同构成MESI(膜萃取吸附剂界面)采样单元。采用加热的硅钢毛细管柱作为传输线，避免了分析物的吸附和冷凝，在检测前对分析物进行了分离。该装置展示了芳香烃、氯化化合物和萜类化合物现场监测的潜力。©2001 John Wiley &儿子,Inc。化学工程学报(英文版)，2001,31 (5):669 - 774
