Accuracy and Application of Threshold Odor Tests

can be measured and odor removal processes evaluated directly by odor measurement. The undertaking involves several inherent difficulties which have not always been recognized, including the variable responses of individuals to identical stimuli. In this paper will be shown the extent to which these difficulties can be overcome and to which reproducible comparative results which are not dependent on the individual, can be obtained. Further will it be shown how these comparative results can be applied to the evaluation of activated carbons or other materials and methods of odor removal.
