Fluorescent sensor based on multi-channel structure

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.
