Particle and gas phase interactions in air sampling.
Air Sampling Instruments 9th Edition 2001 Jan; :77-92
An aerosol consists of airborne particles and sorrounding gases. The particle phase may include solids and liquids. The gas phase normally includes air and water vapor and may include vapors of organic and inorganic compounds as well as contaminant gases, such as sulfur dioxide. The distinction between a vapor and a gas is somewhat arbitrary. Following common practice, the term "vapor" refers to the gas phase portion of a material and atmospheric pressure. A "gas" cannot exist as a liquid or solid at normal conditions.
