Abstract—The aim of this work is to establish a Dynamic Dilution method in which “odor index”(logarithm of odor
olfactometer based on GB. The triangle odor bag method is concentration, multiplied by ten) is measured. In some sense,
described and used in the design of Dynamic Dilution the triangle bags method is not only a measuring method, but
olfactometer. In this paper, we provide detailed instructions for also an important form to propagandize odor pollution
