Chemical Laboratory Technology
Laboratory chemical analysts study substances to determine their chemical composition for research or product development purposes. Chemical analysis is necessary to control the compliance of the properties of raw materials, intermediate stages of the technological process, and finished products with current standards.
Laboratory chemical analysts should be ready to determine the optimal tools and methods for the analysis of various natural and synthetic materials, to perform qualitative and quantitative tests using modern chemical and physico-chemical analytical methods. They need to be well-versed in chemistry and must have adequate knowledge of biology and physics. Critical thinking, time management, decision making, and problem-solving skills are also necessary for this career. Laboratory chemical analysts should be able to act logically and systematically, complying with sanitary and hygienic requirements and occupational safety and health standards.
Laboratory chemical analysts work in the chemical laboratories of quality control departments, research and development departments, or in environmental departments in plants in chemical, petrochemical and pharmaceutical industries. Greater interest in environmental issues, such as pollution control, clean energy, and sustainability, are expected to increase the demand for chemistry research and development.
Competitors and results
The forebears of chemical analysis are alchemists who sought to learn the essence of compositions and substances, conducting experiments and recording the results.
Initially, the periodic system invented by Mendeleev included 56 elements. As new fields of studies developed in the 20th century, the number of discovered elements has reached 118.
Analytical chemistry began to form into an independent science only after the discovery of the law of conservation of mass by the Russian scientist Mikhail Lomonosov in 1748.
The oxygen theory of combustion formulated by Antoine Lavoisier in 1777 lead to a critical point in the development of chemistry called the chemical revolution.
