라벨화된 크기척도법을 이용한 악취강도 평가 가능성

The labeled magnitude scale (LMS) was proposed as the magnitude estimation of perceived odor intensity while thedirect olfactory method is a basis of odor evaluation. Six chemicals (pyridine, ethanol, ethyl acetate, acetone,trimethylamine, and β-phenylethyl alcohol) were tested to demonstrate the limitation of the current odor intensity scaleand the possibility of the alternative method. The 6-point odor intensity reference scale, which is wildly used in thefield, has the inevitable limitation of the perceived magnitude of odor intensity. It has failed to express the magnitudeobjectively when odor intensity increased and the magnitude scale was limited. It was experimentally proven that LMSpresents the function of the existing method and effectively evaluates the wide range of odor intensity.
