Abstract

There is provided a chemical analyzer equipped with a hollow fiber degassing module that can maintain the original degassing performance even after long periods of continuous use, and can also suppress the proliferation of bacteria and the like. More specifically, a hollow fiber degassing module includes a housing and a hollow fiber membrane disposed in an internal space of the housing. The housing includes a liquid supply unit for connecting an outside of the housing and an internal space of the hollow fiber membrane to each other, and for supplying constant temperature water W, a liquid discharge unit for connecting the internal space of the hollow fiber membrane and the outside of the housing to each other, and for discharging constant temperature water, and a gas discharge unit for connecting an internal space of the housing and the outside of the housing to each other, and for depressurizing the internal space.

Dependent claims

A chemical analyzer for performing chemical analysis or biochemical analysis of a specimen, comprising:

a degassing unit including a constant temperature tank for maintaining a temperature of a container containing a specimen, and a hollow fiber degassing module for removing dissolved gas contained in constant temperature water in the constant temperature tank, wherein
the hollow fiber degassing module includes a housing and a hollow fiber membrane disposed in an internal space of the housing,
the housing includes
a first liquid supply unit for connecting an outside of the housing and an internal space of the hollow fiber membrane to each other, and for supplying the constant temperature water from the outside of the housing to the inside of the hollow fiber membrane,
a first liquid discharge unit for connecting the internal space of the hollow fiber membrane and the outside of the housing to each other, and for discharging the constant temperature water degassed from the internal space of the hollow fiber membrane to the outside of the housing, and
at least one first gas discharge unit for connecting the internal space of the housing and the outside of the housing to each other, and for depressurizing the internal space of the housing, and
at least one heating unit provided at the at least one first gas discharge unit is further provided.
