Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas analyzers face issues with continuous analysis due to temperature differences between sample and purge gases, leading to standby times and responsivity deterioration, and clogged gas introduction paths that hinder accurate gas component judgment.
Innovation Solution
An optical cell design with a separable manifold member and heating mechanism that allows easy replacement and adjustment of gas introduction paths, ensuring uniform gas temperature and positioning, and separate introduction and exit points for gases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the sample gas introduction path is integrally connected to the optical cell, then the structural integrity is improved, but the ease of repair deteriorates
Solution Approach 1:
The gas introduction path is divided into a separable manifold member that can be detached from the optical cell. This segmentation allows the manifold member to be easily replaced when clogged, while the optical cell itself remains intact and reusable, thus resolving the contradiction between structural integrity and ease of repair.
2Stability of the object's composition
If the heating mechanism heats the gas for a longer period, then the temperature uniformity is improved, but the analysis time increases
Solution Approach 1:
The heating mechanism pre-heats the gas in the manifold member and gas introduction path before the gas reaches the optical cell. This preliminary heating action ensures that the gas temperature is already uniform and stable when analysis begins, eliminating the need for extended heating periods during analysis and thus resolving the contradiction between temperature uniformity and analysis time.

AI summary
An optical cell is provided which can easily solve a decrease in an amount of gas introduced into an inner space by a gas introduction path and also which can make, relatively small, a temperature difference between various types of gas introduced into the inner space. The optical cell of an elongated shape has an inner space into which gas is introduced and includes: a cell main body forming the inner space; a manifold member being separably connected to an outer surface of the cell main body extending in a longitudinal direction; and a heating mechanism heating the manifold member, in which the cell main body has a through hole penetrating from the outer surface into the inner space, and the manifold member has a gas introduction path extending along the longitudinal direction and guiding the gas, which has been taken in from the outside, from one side to another side in the longitudinal direction and then guiding the gas to the inner space through the through hole.
