COLUMN, GAS ANALYZING APPARATUS AND GAS SEPARATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To realize a column, a gas analyzing apparatus and a gas separation apparatus with which good accuracy can be guaranteed, the downsizing can be achieved and the initial cost and the running cost can be reduced.

SOLUTION: A column for separating gas according to constituents is provided with a flow channel that has a cross section serving as a region in which gas changes from molecule flow into a viscous flow and has a shape of spiral pipe having a curvature radius which becomes continuously smaller from an inlet towards an outlet of gas.
