A model for estimation of the effect of residual odour in sampling bags on odour concentration measurement

Abstract: Based on the European standards, an odor concentration can be expressed as a concentration of the European Reference Odour Mass (EROM). Thus, a “very accurate” odor concentration measurement must be able to be expressed as a continuous value. By comparing the “very accurate” odor concentration measurement and the odor concentration measurement by the standard method, a mathematical model is developed to describe the effect of background odor from manufactured odor sampling bags or residual sample odors from a used sample bag on the sample’s odor concentration measurement at different confident levels.
