Method for detecting malodor from air conditioner, reproducing malodor and preparing corresponding malodor composition

摘要

A method is provided that identifies the compounds contributing to a malodor from an air conditioner, reproduces the malodor, and prepares a corresponding malodor composition. Through the analysis method of the present invention, the compounds contributing to the malodor from an air conditioner are identified and quantified. The malodor is reproduced from a combination of the compounds identified by the analysis method of the present invention. The reproduced malodor provides significant data required for development of an apparatus and a method for removing specific odor.
