Abstract

The apparatus enables accurate determination of concentration profiles of liquid or gaseous substances along a given path. A partially permeable line segment is laid along the route and the substances to be detected are allowed to penetrate into its interior. The line is filled with a test medium, and the column of the test medium is forced through the line at chronological intervals and moved past a sensor that is sensitive to the substances. A first closure is incorporated between the sensor and the line, and one or more closures are incorporated into the line to maintain the column of test medium substantially stationary in a position of repose of the system.
