Particulate Contaminant Descriptions and Definitions

  • Alvin Lieberman


Particulate contaminants can be either solid or liquid. Many of these materials were originally suspended in air or in a process fluid; others derive from nearby sources, such as activities of personnel working in the cleanroom or operations of process equipment. Until particles are about to contact a product or already have been deposited upon that product, some schools of thought consider that any particles remote from critical areas are not really contaminants, but simply environmental components. Even so, because the fluid in which they are suspended will probably contact the product sooner or later, it is necessary to keep that fluid as clean as possible.
