This is an experimental study which was undertaken to determine if a gas chromatographic technique could be used to measure paperboard odor levels. Because there are many variations to odor testing using a panel of judges - which is the generally accepted method - the author states that, obviously, an objective method for ascertaining odor levels would be a valuable tool. Paperboard odor levels were evaluated by gas chromatography using head space sampling techniques. Samples were rated according to relative response factors of the odoriferous components. A good correlation was obtained between this gas chromatographic method and an odor judging panel. Standard techniques were used in selecting, training, and using the panel. One conclusion reached was that this method has practical applications, and can be used in finding odor sources. (LK)
