The main discipline of chemistry is analytical chemistry. The focus is on quantifying the amount of a desired molecule in a natural sample, laboratory material or substance. Gas chromatography, gas chromatography mass spectrometry, mass spectrometry, and atomic absorption spectrometry are technologies used in analytical chemistry.
A relatively recent, but vital, new concept, organic chemistry, has emerged from alchemy with many modern concepts. The term organics refers to organic compounds, which are characterized by the presence of carbon in its physical form. It is the study of the chemical properties of solid organic molecules, crystalline inorganic complexes and molecular ionic solids containing organic functional groups. The earliest suggestions of the existence of organic matter on Earth can be found in the writings of alchemists. The study of organic chemistry was traditionally associated with organometallic chemistry, organic biochemistry, and the natural sciences. In the twentieth century, organic chemistry became a main highly organized discipline in organic chemistry. In the 21st century, organic chemistry is the most studied and taught discipline in chemistry departments in the world.
In chemistry, the division between organic and inorganic compounds is a matter of convenience. Many inorganic compounds contain carbon atoms, and many organic molecules are not composed of carbon. There is no sharp distinction between the two groups. Instead chemistry teaches the characteristic qualities that arise from their distinct differences.
In organic chemistry, carbon forms the basis of life and is the most important component of the Biosphere. It is also the only element heavier than helium that is a natural product (except tiny quantities in meteorites); and its physical, chemical, and biological properties form the basis of organic chemistry. d2c66b5586
