Description

FIELD OF TECHNOLOGY

The invention relates to the field of analysis of the composition of liquids, and in particular, to methods that provide reliable, safer and faster determination of the presence of various substances in solutions in solutions and can be used for rapid testing of alcohol-containing products and drinking bottled water for the presence of impurities, including harmful, as well as other liquid food products, in addition, liquid pharmacological, cosmetic, liquid fuel, oils.

BACKGROUND OF THE INVENTION

Methods for testing the composition of liquids are well known. A number of methods are based on spectral analysis, for example [1], and methods using laboratory research methods, for example, dielectric permeability measurements [2], are also known. These methods, with their high accuracy, have significant drawbacks due to their high complexity and the need for expensive and bulky equipment, which does not allow their use in mass application, in everyday life, outside special laboratories. A number of chemical methods are known for determining impurities in liquids using chemical reagents, for example, [3, 4]. However, their common shortcomings are low performance due to the performance of express analysis regardless of the use of the analyzed object in time and space due to their physical incoherence, which makes such methods also exclusively laboratory, and therefore impossible for the mass consumer in a domestic environment.

A known indicator strip is an express analysis of solutions, characterized in that it is made in the form of a multilayer voice made of glued or welded together two or more transparent, dull or colored materials in the form of polymer films, inside of which indicator zones consisting of several layers are isolated in an amount from one to five, containing the necessary chemicals in the right concentrations for quantitative or qualitative determination of the composition of the analyzed solution s, and the layers are made of a combination of both absorbent and non-absorbent, mesh or non-woven materials, while the number of indicator zones, depending on the number of analyzed components, is from one to fifteen. In addition, a film for cold lamination is used as the outer layer of the strip. In addition, a hot lamination film is used as the outer layer of the strip. In addition, a film without an adhesive layer is used as the outer layer of the strip. In addition, a double-sided film for hot or cold lamination is used as the inner layer of the strip; porous or mesh polymer material is used as the outer layers of the strip. In addition, white laminated paper is used as one of the outer layers of the strip. In addition, absorbent paper laminated on one side is used as one of the outer layers of the strip. In addition, color standards are used as one or more indicator zones [5].

The well-known utility model allows for simple and fast enough rapid analysis of liquids for the content of certain chemicals in the form of dissolved impurities, however, it has low operational characteristics, since the indicator strip itself does not contain any motives for testing as well as the test object , since the testing tool and the test object are not connected in any way. As a result of this, the method of using the known device and the device itself have low functionality due to low versatility and the need to select strips for the type of liquid under investigation each time with each single rapid analysis procedure, which also increases its time, reduces the simplicity of express analysis by the need for individual selection and search strips. It also reduces the reliability of the known device and method of its use due to the fact that the object of study is not connected with the analysis tool, errors in the use of inappropriate indicator strips are possible, which is of great importance in the food and chemical industry and can pose a serious threat to human health and life.

The closest is the known method implemented in the ionizing indicator, namely, that the marker is combined with a container. The ionizing indicator is characterized in that it is made of silver (Ag) and consists of a logo connected by means of a connecting link to a supporting element, and a float made of natural material or polymer is attached to the supporting element, and the logo and supporting element contain an indicator. In addition, the logo of the ionizing indicator is made in the form of a medal, trademark, badge, order. In addition, the float is a cork tree or may be made of a material with similar properties. In addition, the supporting element can be made rectangular, square, triangular, zigzag. In addition, the float, together with the logo attached to it and the supporting element, when placed in a liquid, acts as an indicator showing the density of the liquid, being at a predetermined level in a container with a liquid containing alcohol. In addition, the logo is made of silver and when placed in a water-alcohol solution performs the function of saturating the solution with silver ions. In addition, the logo, the supporting element, the connecting link are made of precious metal, subject to mandatory testing and can implement the anti-counterfeiting function. In addition, in addition, the indicator can be manufactured using a chemical element that signals the presence of harmful substances in the liquid. In addition, the indicator can be made of a polymer that changes color depending on the temperature of the liquid. The method of using this device is that inside the container is a bottle, a transparent container, containers, etc. position the hydrometer and observe the position of the internal float, while the hydrometer is made of silver, which contributes to the saturation with silver ions of the liquid contained in the tank. In addition, the float may have a temperature-dependent coating so that its color depends on the temperature of the liquid, that is, it indicates the storage conditions. In addition, the float may contain a chemical reagent, indicating the presence of harmful substances in the liquid [6].

With all its advantages associated with combining the means of express analysis with a container containing a controlled liquid, the disadvantages of the known method and device include low safety (which is unacceptable, especially for the food industry) due to the constant exposure of the chemical reagent in contact with bottled liquid. In addition, this also determines the low service life of the device and, consequently, the efficiency of the method is reduced to almost zero, since, in accordance with the known method, the chemical reagent dissolves and / or decomposes quite quickly and ceases to perform its functions. In addition, a significant drawback is the low functionality and low accuracy of rapid testing in relation to the substances contained in the liquid, since the known method and device control the composition of the bottled liquid, primarily by its density (hydrometer), which is low informative in relation to those contained in liquid impurities and practically do not allow to control their presence.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

The method of rapid testing of bottled liquids is as follows;

In the first embodiment, on the surface of the container 1, closed with a stopper 2 and provided with a label 3 (Figs. 1, 2, 9-16) containing bottled liquid 4, an indicator strip 5 is impregnated with reagents corresponding to the required class of rapid testing of this type of liquid. Strip 5 may contain a protective coating 6 (Fig. 2-4, 6-8, 11-15), which is removed during the rapid test (Fig. 11-15) and on which the instruction for use, trademark, advertisement can be printed etc. Also, the protective coating 6 of the test strip 5 can be made in the form of an excise stamp (Fig. 9). Next, the stopper 2 is opened and a small part 9 of the liquid 4 is poured from the container 1 into a separate container 7 (Fig. 10), followed by the separation of the protective coating 6 from the test strip 5 located on the container 1 (Fig. 11). After that, the test strip 5 is separated from the outer surface of the container 1 (Fig. 12-14) and lowered into a separate container 7 containing a small portion 9 of bottled liquid (Fig. 15). After a time determined by the type of rapid testing, strip 5 is removed and, based on a change in its state (color 10), one or another impurity or complex of impurities is judged (Fig. 16).

In the second embodiment, the test strip 5 is preliminarily placed on the inner surface of the container 1 regardless of its immersion in the liquid or not (Fig. 3, 7). In this case, the test strip must be hermetically coated with a protective coating 6, for example, with a polymer film chemically compatible with the liquid 4 contained in the container 1. In this case, the strip 5 with the protective coating 6 is mechanically connected to the stopper 2 on the inside of the container 1. The connection can be carried out directly ( Fig. 3, 7), or using thread 8. In a variant of the method, the test strip 5 is freely placed inside the container, without fixing it on the inner surface (Fig. 4, 8). When performing the method of rapid testing, when opening the plug 2 and separating it from the container 1, the test strip 5 coated with a protective coating 6 is simultaneously removed. After that, part 9 of the liquid 4, sufficient for rapid testing, is poured into a separate container 7. Next, separate strip 5 from the protective coating 6 and lower part of it into a part of the liquid located in a separate container 7 (Fig. 15). After a period of time sufficient for the reaction of the impregnation of the strip 5 with the liquid 4, the strip 5 is removed and the changes in its state (for example, color 10) are judged on the presence of 4 impurities in the test liquid (Fig. 16).

The method can be combined, combining the operations of the first and second options, using two or more strips containing different reagents to expand the range of impurities to be determined. In this case, all the strips can be placed on the outer surface of the container, or only on the inner surface, or by combining the location of part of the strips on the inner and outer surfaces of the container. Various combinations are possible with the arrangement of all or part of the strips inside the container, without connecting them to the inner surface and in combination with all other possible options.

A specific example of the best method.

As the tested bottled liquid was used vodka 0.5 l (Fig. 9). The test strip was positioned vertically separately from the label, placing it under an excise stamp. After opening the bottle stopper and pouring part of the liquid into a separate container (glass, Fig. 10), the excise stamp (Fig. 11) was removed, which is the protective coating of the test strip and the protective strip was separated from the surface of the bottle (Fig. 12-14). After that, part of the strip (about one third) was immersed in the tested part of the liquid in the glass (Fig. 15). Within a few seconds, a color change occurred in the immersed part of the test strip, which was clearly visible after its extraction (Fig. 16), as a result of which it was possible to judge the presence of methanol in vodka in this individual test bottle.

Thus, thanks to the proposed method, it was possible to carry out, on the one hand, the combination of the testing agent with each bottle with bottled liquid, which made it possible to simplify, speed up, increase the motivation of rapid testing, and increase the safety of using liquids. On the other hand, the proposed method gives all these advantages the opportunity to increase the accuracy and safety of the test itself, since it does not require the placement of the reagent directly in the liquid, and allows you to use only a small part of it for rapid testing, which is then not used for its intended purpose, but allows you to judge the presence of impurities in the entire volume of the tested fluid. All this allows you to achieve the goal of the invention and obtain the claimed technical result.

The advantages of the proposed method of rapid testing of bottled liquids in comparison with known methods, including the prototype, are:

- increased safety of the method due to the complete elimination of constant contact of the reagent with the test liquid, which is typical for the prototype method implemented in the known device. This is of great importance, especially in the food and chemical industries and completely eliminates the pollution of the bulk of bottled liquids and the diffusion of foreign substances in them from the testing reagents, since the combination of the testing tool with the test objects is not carried out continuously in the proposed method in monitoring mode, but only directly during the testing process. This is also due to the fact that direct testing, that is, direct contact of the test liquid with the reagent, is carried out in the proposed method only on a small part of the liquid separated from the main volume, however, this allows us to judge the content of impurities in the entire liquid.

- increased accuracy of express testing, since it becomes possible to virtually eliminate the passage of containers without express testing by placing testing tools directly on containers with bottled liquid, and also eliminates the possibility of mixing test strips for the wrong type of liquid;

- increased performance due to the proposed operations of the method in the proposed order, the simplicity of rapid testing is significantly increased, since the need for search and selection of strips for a specific type of liquid during the testing disappears, as this is already done in advance when bottling liquids. This also leads to a significant reduction in the time of rapid testing;

- increased reliability of rapid testing by increasing motivation due to the physical combination of testing tools with the test object in the most simple and convenient way for the consumer, which allows almost always to control the quality of bottled liquid immediately before use;

- enhanced functionality by increasing the versatility of the method, which allows the method to be implemented by introducing a greater degree of standardization, which, in turn, allows to expand the range of applicability of the method for various types of bottled liquids;

- significant opportunities for increasing the mass and prevalence of rapid testing of bottled liquids of various types and its simplicity, which can significantly improve public health by simplifying the determination of harmful impurities in bottled liquids of the food and pharmaceutical industries to the household level and introducing an element of forced testing into the testing process obligatory.
