Comparison between Method of Triangle Odor Bag and Method of Dynamic Olfactometry for Odor Concentration of Air

In order to compare Method of Triangle Odor Bag with Method of Dynamic Olfactometry in odor concentration of air,we compared the uniformity and difference by using the method of real air sample and least significant difference.The results demonstrated that the Method of Dynamic Olfactometry was in accordance with the Method of Triangle Odor Bag(P0.01),So it is suggested that the Method of Dynamic Olfactometry can be used as a standard method for evaluating odor concentration.
