Abstract

A system and method for collecting a sample of a fluid comprising a sampling apparatus for use in natural or man-made bodies of fluid comprising a polymer-based or metal collection capillary, a capillary filling means attached to said capillary and at least two collapsible sample demarcation indicators affixed to said capillary. The apparatus of the instant invention is deployed by first inserting a polymer-based or metal collection capillary below the surface of the fluid body from which a sample is to be withdrawn then filling the capillary using the capillary filling means, monitoring the flow of fluid from the fluid body to the internal chamber of the submerged collection capillary and then causing the cessation of said flow.
