本文建议将化学敏感层与普遍适用的质量敏感装置相结合，用于液体多组分分析的集成系统的发展。完全可逆的固相萃取用于通过溶胶-凝胶相检测离子是可能的。这些层应用于石英微天平(QMB)的一步处理过程中，显示出极好的灵敏度，并且不会受到渗漏影响。对于水中多环芳烃(PAHs)的测量，提出了一种通过使用双压印层来产生选择性的新概念，该概念允许调节额外的参数，如对主体的可访问性。通过模板分子的不同组合，可以产生每一种所需的多环芳烃选择性图案。(C)2001 Elsevier Science B.V.保留所有权利。
In this paper chemically sensitive layers in combination with universally applicable mass-sensitive devices are suggested for the development of integrated systems for multicomponent analyses of liquids. Completely reversible solid-phase extraction for the detection of ions by sol-gel phases are possible. The layers, applied to the quartz microbalance (QMB) in a one-step process, show excellent sensitivity and do not suffer from bleeding effects. For the measurement of polycyclic aromatic hydrocarbons (PAHs) in water, a new concept of generating selectivity is presented by the use of double imprinted layers, which allows to tune additional parameters such as accessibility to the bulk. By different combinations of template molecules every desired PAH selectivity pattern can be generated. (C) 2001 Elsevier Science B.V. All rights reserved.
