Dry Air
Dry air refers to the mixture of elemental gases (nitrogen, oxygen, argon, carbon dioxide, neon, helium, krypton, xenon) present in the atmosphere under normal weather conditions. This mixture of gases is often called "dry air".
Physical Properties
-
Colorless and Odorless: Dry air is colorless and odorless.
-
Composition: Usually 78% nitrogen, 21% oxygen, 1% other gases (including argon) and trace gases (carbon dioxide, neon, helium, etc.).
Production
-
Air Distillation: Air from the atmosphere is distilled at low temperatures in specialized plants. This process usually isolates components such as nitrogen, oxygen and argon.
Areas of Use
-
Laboratories and Industrial Processes: Dry air is used as a kind of carrier or purifying gas in many laboratory applications and industrial processes.
-
Pharmaceutical Industry: It is used in pharmaceutical production, especially in precise measuring and mixing processes.
-
Food Packaging: During the packaging of food products, it is used to control the environment inside the packaging.
-
Chemical Analysis: It can be used as a carrier gas in chemical analysis, especially in methods such as gas chromatography.
Safety
-
Dry air is generally considered safe because it contains the normal components of air in the atmosphere.
-
However, certain industrial processes may require the use of pure air.
Dry air is an essential gas mixture used in many industrial and laboratory applications. It is especially important for maintaining a stable environment in precision measurement and analysis processes.
