摘要
FIELD: physics, measurement.;SUBSTANCE: invention is related to the field of ecology, namely to portable facilities used for air express-analysis for availability of hazardous substances. Indicator flat elements (IFE) comprises polymer container that consists of two parts that are fixed along external layer and create a cavity between each other, in which the following components are located: indicator ticket made of nonwoven polymer material having high sorption ability, filtering pad installed substantially parallel to indicator ticket, and sealed reservoirs installed between indicator ticket and filtering pad, which represent ampoules or sealed bags made of combined metallised material, which contain indicator solution and not necessarily water and/or buffer solution; besides, on opposite sides of polymer container in its every part there is at least one opening for air access, moreover, opening in one part is covered with indicator ticket, and in the other one - by filtering substrate. Sealing of IFE is provided by means of its soldering into bag made of metallised polymer material. Invention is also related to set and kit that comprise IFE as per invention, and also to method of air express-analysis with application of specified IFE.;EFFECT: simplification of indicator flat elements (IFE) usage, improved ergonomic characteristics of device, higher reliability of control repeatability and sensitivity.;73 cl, 2 dwg
