Abstract
Official abstract text for this publication.
A conventional solution exchanging method in a next-generation sequencer needs a reagent amount four or more times greater than an in-flow cell flow passage volume in order to efficiently promote a chemical reaction by replacing a reagent A in the flow cell with a new reagent B. Thus, the reagent consumption amount increases, and the cost is high. Meanwhile, an analysis apparatus according to the present invention is provided with: a flow cell used for analyzing samples; a sample container for containing a sample; a reagent container for containing a reagent; and a pressure generation mechanism for feeding the sample and the reagent to the flow cell through the flow passage, and also has an atmospheric opening in the flow passage of the flow cell on the upstream side.
