Description

The claimed technical solution relates to the field of chemical industry, namely to indicator devices used in colorimetric analysis of air for the presence of substances.

Known indicator devices (indicator elements, indicator papers, indicator tubes, etc.) for the qualitative and / or quantitative determination of the content of substances in environmental objects (1-13).

Analogs of the claimed technical solution are indicator papers and indicator elements (5, 7, 8).

The indicator flat element IPE (13) is designed to control harmful substances, namely nerve gases. IPE is a plastic strip. One half of the plastic strip contains two paper disks, one of which is impregnated (impregnated) with the enzyme solution, and the other with a pink substrate, an ampoule containing the reagent is attached to the other half of the plastic strip. The reagent ampoule is located in the tube, which helps the reagent solution to drain onto a paper disk impregnated with the enzyme solution. Each IPE is stored in an individual waterproof package.

From a comparison of the characteristics of the analogue with the essential features of the proposed solution, it follows that they have layers of a porous base, impregnated with indicator substances and bonded to each other.

The disadvantage of such elements are:

- uneven wetting with a reagent solution of a paper carrier when breaking an ampoule;

- low reliability of the analysis result due to the need to manually bend a plastic strip to connect paper disks;

- reduced usability, namely opening the ampoule, wetting the paper disk, compressing the plastic strip and holding it in a certain position, which are done manually.

The closest analogue selected as a prototype of the claimed technical solution is an indicator flat element (12) containing a polymer container consisting of two parts, one-piece connected (for example, soldered, fused or glued) together along the outer edge and forming a cavity in which are located:

- indicator ticket (primary chemical converter);

- a filter substrate located parallel to the indicator ticket, and at least one sealed container, which is an ampoule or a sealed package of combined metallized material containing an indicator solution and, optionally, water and / or buffer solution;

- indicator ticket is made of non-woven polymeric material having high sorption ability;

- on opposite sides of the polymer container in each part is made at least one hole for air access;

- the hole (s) in one of these parts is blocked by an indicator ticket, and the hole (s) in another part is blocked by a filter substrate;

- a sealed container (sealed containers) is located (located) between the indicator ticket and the filter substrate.

A comparison of the features of the prototype with the essential features of the proposed solution shows that both of them have a layer of polymer porous material with the structure of ultra-thin fibers and filter material.

The disadvantages of the prototype are:

- the offset of the upper flat parts during welding, which reduces the manufacturability of the Assembly and use of the element,

- reduction in structural rigidity.

The technical result of the development of the proposed technical solution are:

- improving the manufacturability and assembly of the element;

- increasing the rigidity of the design of the element;

- increased ergonomic use of the element;

- improving the reliability of the determination of substances.
