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.

Method and device for isolating and analyzing target substance in solution

Provided is a phosphor for scintillator that can absorb radiation and convert it into visible light, and which has a short fluorescence decay time. The phosphor contains a lutetium sulfide-containing host material and an activator agent ion, for example, a phosphor comprising a composition represented by the general formula (LuPr)S, or (LuCe)S.
