An apparatus provides for the detection, the determination of the location or the spatial distribution, and/or the quantification of an amount of a chemical species by allowing the chemical species to come into contact with a fluid medium contained in a permeable capillary, transferring the content of the capillary after the contact to a detector, and detecting the chemical species as the content of the capillary is transferred to a detector. The fluid medium can contain a selected reagent that selectively interacts with the chemical species to produce an optically detectable interaction product. The location and amount of the chemical species are determined from a characteristic of the chemical species or its interaction product measured on the content of the capillary and the time at which the characteristic is detected. The apparatus may be used in a method for detecting, determining the location or the spatial distribution of, and quantifying a wide range of chemical compounds, such as for monitoring chemicals in environment and industrial facilities and determining products in a combinatorial experiment.
有一种仪器可以检测、确定化学物质的位置或空间分布,和/或量化化学物质的数量,其方法是让化学物质与可渗透毛细管中的流体介质接触,接触后将毛细管中的物质转移到检测器中,当毛细管中的物质转移到检测器中时检测化学物质。流体介质可以含有选择性试剂,该试剂可选择性地与化学物质相互作用,产生可光学检测的相互作用产物。根据在毛细管内容物上测量到的化学物质或其相互作用产物的特征以及检测到该特征的时间来确定化学物质的位置和数量。该装置可用于检测、确定各种化合物的位置或空间分布以及量化各种化合物的方法,例如用于监测环境和工业设施中的化学品以及确定组合实验中的产物。
