FIELD: chemical analysis, nonbiological materials analysis.
SUBSTANCE: test-band consists of a wafer, on end of which is fixed a reagent paper indicator for detecting ions of the specific metal, as well as a layer of an accumulating liquid and the surrounding medium, fixed opposite the reagent paper indicator on a section of the wafer with provision to exert pressure on the layer of the accumulating liquid, which is placed over the section of the wafer, on the lower side of which is fixed the reagent paper indicator. There are through-passing coaxial openings in the layer of the accumulating liquid and the polymer wafer.
EFFECT: increased quantity of analysed objects with simultaneous increase of authenticity and reliability of the obtained results.
