ABSTRACT:
A sample introduction system comprises a sampling circuit and a carrier stream circuit where the two circuits share a volumetric conduit which is at all times connected to and simultaneously opened to both sampling and carrier circuits. This system allows, by a controlled combination of hydrostatic and hydrodynamic forces, to create a well-defined sample zone within the volumetric circuit and then to transport this zone, in a well-reproduced manner, into a continuous flow analyzer where an assay of sample solution components may be performed quantitatively, if necessary even with the aid of chemical reactions, from the signal as provided by a flow-through detector.
