Abstract: A transport system is provided in which a plurality of samples are introduced into a carrier stream flowing through a conduit, whose inner surface is coated with an immiscible liquid film. The carrier stream can be a sequence of alternating gas and liquid segments which are in direct contact with each other and, thus, not encompassed by the immiscible liquid. Samples are introduced at various points along the conduit and, thus, the system allows for the collection and transport of samples from a plurality of remote locations to at least one central receiving station where they can, for example, be analyzed. Carryover between successive samples to be transported is effectively eliminated.

Abstract: Apparatus and method for obtaining a concentration gradient in a liquid sample analyzer including flowing a first liquid in a stream to fill a conduit, and continuing the flow of the first liquid along the conduit subsequent to the filling step. combined with these steps is the step of changing the concentration of the first liquid by removing from the stream a predetermined varying volume of the first liquid and adding to the stream a predetermined proportional varying volume of a second liquid. There is also provided a method of serial dilutions of a liquid stream in a conduit by removal of a portion of the stream prior to each diluent addition for the purpose of conserving diluents which may be reagents.

Abstract: A liquid substance is transferred from a first carrier stream to a second carrier stream. The transfer includes the use of a movable conveyor and the flow of a deposited volume of the first stream along a portion of the conveyor as a sheath stream.
