Abstract

PURPOSE:To prevent the inclusion of gases from the outside during analyzing of gaseous components and perform analysis in a short time by providing a case with a test liquid injecting tube, and analyzing gas supply tube and a holding plate holding an analyzing gas for a constant time. CONSTITUTION:While coloring liquid is being supplied from a coloring liquid injecting tube 6, an internal gas is exhausted from a gas exhaust tube 8, and after the coloring liquid is injected to a constant amount, an analyzing gas is released from a gas inflow tube 9 into the coloring liquid. This gas forms gaseous bubbles in the coloring liquid and these bubbles ascend while contacting with the coloring liquid and accumulate on the bottom surface of a holding plate 11. While the bubbles and the coloring liquid are in contact, the intended component in the gas reacts with the coloring liquid and forms a color. The gaseous components other than the intended component are exhausted from the tube 8. Thereafter, the absorbancy is measured by using the light of the wavelength corresponding to the coloring liquid past the optical path part A of a vessel 1. Thereby, the operation time is reduced considerably, and the inclusion of the gaseous components from the outside is eliminated.
