1. Method of continuous flow analysis of a liquid sample in a carrier stream, said method comprising the steps of:
- forming said carrier stream as a continuous unobstructed flow of liquid in a tube, said flow being turbulent at a predetermined station within said tube andinjecting said sample through a wall of said tube into said stream as a discrete volume at or upstream from said station.

Abstract
A continuous flow analytical system in which there is provided a continuous unobstructed carrier stream into which discrete volumes of sample solutions to be observed for reaction with the carrier stream are injected successively. A detector for measuring the results of any reaction between the carrier stream and sample solutions is positioned downstream from the point of injection.

7. Apparatus for continuous analysis of a sample solution in a carrier stream, said apparatus comprising in combination;
-
means providing a continuous unobstructed liquid carrier stream; a flexible walled tubular conduit; means for pumping liquid from said source through said conduit so that the flow through at least a portion of the latter is substantially turbulent; and means for injecting a predetermined volume of said sample solution through a wall of said flexible conduit and into the carrier stream within said conduit upstream of or in said turbulent flow. - View Dependent Claims (8, 9)
