A Simplified Method for Estimating Intensity of the Lingering Cigarette Odor

The method developed to analyze the components of cigarette odors is capable of quantitatively evaluating lingering odor using a simple procedure. The odor intensity is then estimated by condensing the gas evaporated from curtain material previously exposed to cigarette odors and subsequently analyzing the gas with gas chromatograph mass spectrometry. The lingering odor has been confirmed to contain aldehyde, olefin, heterocyclic and heteroaromatic compounds. After confirming the linear correlation between the logarithm of vinyl pyridine concentration and the six-level odor intensity, a simplified method of estimating the intensity of lingering odors has become possible by using the vinyl pyridine concentration.
