Automatic analysis device and automatic analysis method

Abstract

There are provided a hollow fiber degassing module that is superior in chemical resistance and allows for reduced contamination even in extended use in the degassing of constant temperature water, the automatic analysis device that includes it, a (bio)chemical analysis method in which this automatic analysis device is used, and a method for degassing the constant temperature water. To be exact, an automatic analysis device that carries out chemical analysis or biochemical analysis of a specimen, a (bio)chemical analysis method in which this automatic analysis device is used, and a method for degassing the constant temperature water include a constant temperature tank for maintaining a test tube containing the specimen within a certain temperature range and a degassing portion including a hollow fiber degassing module for removing dissolved gases contained in constant temperature water in the constant temperature tank, the degassing module including polyolefin resin or fluoropolymer hollow fiber membranes.
