Fluorescent sensor on basis of multichannel structures

摘要

Sensor 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 has multichannel structure in a form of a piece 1 of a 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 layer ( 3 ) is formed of organic substance. The first of the layers in microchannels contains sorbent microgranules 5.
