Luftfraktion

Luftfraktion is a term used in Germany to describe the fractional composition of air. This refers to the relative amounts of different gases present in the Earth's atmosphere. The primary components of dry air are nitrogen (approximately 78.09%), oxygen (approximately 20.95%), and argon (approximately 0.93%).

Other gases are present in much smaller, trace amounts. These include carbon dioxide (around 0.04%), neon, helium, krypton, hydrogen, and xenon. Water vapor is also a significant component of the atmosphere, but its concentration varies widely depending on temperature and location, so it is often excluded when discussing the standard Luftfraktion of dry air.

Understanding the Luftfraktion is important for various scientific and industrial applications. For instance, in combustion processes, the amount of oxygen available directly impacts efficiency and emissions. In atmospheric science, the precise composition of air is crucial for studying climate change, air pollution, and atmospheric chemistry. Technological processes like air separation units rely on precisely separating these gases based on their distinct properties and concentrations. The study of Luftfraktion also plays a role in fields like aviation and meteorology.
