Fluorescent sensor on the basis of multichannel structures

摘要

Sensor is intended for use in highly sensitive analytical devices for qualitative and quantitative analysis of natural waters and technology-related solutions, containing low concentrations of components determined. <??>Design of a sensor provides for simplification and costs reduction of its manufacture, widening range of solutions analyzed, improvement of their kinetic characteristics and increase in analysis sensitivity. <??>Sensor comprises multichannel structure in the form of a length 1 of polycapillary tube with through capillaries forming microchannels filled up with two layers of immiscible substances. One layer (4) is formed of water or aqueous solution, and another (3) - of organic substance. The first of said layers in microchannels contain sorbent microgranules 5. <IMAGE>
