Precipitation separation type continuous flow analytical apparatus and quantitative analysis of thiourea in copper electrolyte

摘要

A flow injection analytical apparatus which is capable of continuously performing flow analysis of a sample, produces precipitates during the flow through a capillary. The precipitation separation type continuous flow analytical apparatus has a sample injection portion, a reagent addition portion and an analytical portion which are integrally communicated by a measurement pipeline to form a measurement system. A precipitant addition portion and a filtration portion are provided between the sample injection portion and the reagent addition portion in order to continuously perform production and filtration of precipitates during flow of the sample solution to the reagent addition portion.
