The world without analytical chemistry. Apocalypse? I Dare to claim
that each of us... analytical chemist. Where? In kitchen or if to prepare laziness for you, behind a dining table: “Something, the hostess, solets is not enough: nedosol on a table - peresol on a back“! You feel? Already we analyze: amount of salt in food, sugar in tea, quality of cognac, degree of rottenness of egg.
D. I. Mendeleyev spoke: “… to look for something - at least mushrooms or any dependence, it is impossible differently as watching and trying “.
The analytical chemistry develops methods of definition of a chemical composition of substance. It arose before other chemical sciences (until the end of the 18th century the chemistry was defined as the science studying a chemical composition of substances ). N. Voklen in 1799 wrote the first “Introduction to analytical chemistry“. Historically it is first scientific actually chemistry . Includes the qualitative analysis and the quantitative analysis. Now there are over 300 methods of research and control of a chemical composition of substance.
This section gives rise to the next branching of chemical knowledge - of analytical chemistry of elements . The institute of geochemistry and analytical chemistry of the Russian Academy of Sciences (GEOHI, Moscow) publishes a series of monographs which there are over 60 already now, and ideally has to be 116 - on number of the known chemical elements.
Throughout nearly all history of analytical chemistry one of its most important tasks consisted and consists in establishing connection between structure and any easily measured property and to use the revealed regularities, that is these communications, for development of ways of determination of concentration and the corresponding devices.
Sensors, or chemical sensors which give direct information on a chemical composition of the environment (solution) in which the sensor, without selection of the analyzed test and its special preparation is shipped belong to such devices, for example. Achievements in adjacent areas (physics of a solid body, microelectronics, microprocessor equipment, materials science) led to emergence of the new direction in analytical chemistry - “ of chemical sensors “. Touch analyzers can independently work, without intervention of the operator, and it is supposed that they are connected with systems of accumulation and the automated information processing. “electronic language“ and “an electronic nose“ - elements of “electronic kitchen“ are developed. Adjusted such sensor under the taste - and soup is moderately salted.
In the world tens of Magazines of analytical chemistry in all main languages of Earth are issued. In Russia, except the GEOHI central Institute, scientifically - research and control analytical departments and laboratories exist in all organizations dealing with substance and on all chemical (including bio - geo - eko-) productions.
The dreadful scenario of a modern civilization is representable. The analytical chemistry … is forgotten. Metallurgists remain without express - the analysis - there are no modern metals and alloys. There are no planes and cars also they and are not necessary as oil refineries rose without control chemical laboratories. There are no computers and mobile phones - purity of silicon for chips could not be defined. We breathe muck, we drink and we eat a poison - there is nothing to define quality of air, water and food. The people come back to a subsistence economy, and the population of Earth is reduced to prescientific level - one billion people. Six billion die out.
Here such of the chemist - an analytical apocalypse .
