Abstract: Provided is a flow analyzer and a flow analysis method each of which makes it possible to stably and continuously measure a sample. The flow analyzer and the flow analysis method each include: a marker introducing device (2) which is for introducing a marker into a tube (3); and a marker detecting device (5) which detects the marker and outputs a detection signal to an analyzing device (4), the analyzing device (4) acquiring analysis data on the basis of the detection signal.

Abstract: The object of the present invention is to provide a novel flow analysis method and a novel flow analyzer each of which makes it possible to improve accuracy of an analysis. A flow analysis method in accordance with an embodiment of the present invention attains the above object by including: a sample introducing step of introducing a sample into a tube (100); a reagent adding step of adding a reagent to the sample which is transferred through the tube (100); and an analyzing step of quantitatively or qualitatively analyzing the sample to which the reagent has been added and further including, after the reagent adding step and before the analyzing step, a gas-liquid separating step of sequentially removing gas which is present in the tube (100).

Abstract: There is provided a separation method in which a target component in a solution can be separated simply but safely and efficiently without contamination from the environment. This method includes: providing a solution containing a target component, and a reaction reagent; while continuously feeding the solution and the reaction reagent to a flow path, intermittently injecting bubbles into the flow path to produce a gas-liquid slug flow in which a mixed liquid containing the solution and the reaction reagent is segmented into a plurality of droplets by the bubbles; continuing the feed of the gas-liquid slug flow in the flow path, thereby facilitating the mixing of the solution and the reaction reagent, and the gasification of the target component by the mixing, in each droplet, and the movement of a target component-derived gas produced by the gasification to the bubbles; and recovering the target component-derived gas with an absorbing liquid.
