The paper is devoted to tentative results of implementing a new kind of optical analytical method - digital color analysis (DCA), in which, as an optode, membranes are used that are created of reagents immobilized on optically transparent solid polymer matrices. Interacting with a substance under investigation the immobilized reagents change the matrix color. This color change indicates a content of a component determined and persists for a long time. The color difference obtained can be transformed to numerical value that is treated as analytical information. DC-analyzer works in similar way as the human eye which rather precisely discriminates colors in spite of a possible spectral complexity of the optical signal. The registration of not reflection and transmission of the light radiation through transparent optodes is promising to reach by 1-2 orders of larger sensitivity at low optical absorption.
