INDICATOR SENSITIVE MATERIAL FOR PROXIMITY TESTING OF TRACES OF SUBSTANCE Russian patent published in 1996 - IPC

FIELD: chemistry, agriculture, medicne, food industry, ecology. SUBSTANCE: inventioncan find use anywhere where fast quantitative or semi-quatitative testing of microconcentrations of substance is required. Proposed indicator sensitive material for proximity testing of microconcentrations of substances provides for maximum sensitive visual testing of substances thanks to increase of contrast of colour reactions while inspecting natural or industrial objects. Indicator sensitive material includes solid carrier, organic reagent and optical bleacher-belophor with following proportion of components, per cent by mass: carrier 91.0-96.0; bleacher 1.0-2.0; organic reagent 3.0-10.0. EFFECT: expanded application field, increased graphicality of testing. 2 cl, 1 tbl
