An apparatus for the rapid determination of the compactness of cigarettes is presented. We may recall to mind that the compactness of a cigarette is the subjective measure of its filling regarded as average value of the whole of the cigarette. It does not take into account irregularities along the paper wrapping. The compactness thus applying to the total of cigarette filling has direct relation to the degree of exploitation of cut tobacco. In view of an optimum control of manufacture it is desirable to determine cigarette compactness by representative samples. The apparatus meets these requirements. It permits to measure the average compactness of a sample of 15 cigarettes in a short time and holds a device for the determination of tobacco humidity by which compactness values can be referred to a given standard of moisture. The apparatus is suitable for direct utilization in the factory

The present paper describes a simple device designed for the analytical smoking of single cigarettes and capable of collecting the gaseous constituents of tobacco smoke. The trap has been used to determine the carbon monoxide content of the smoke of cigarettes made from reconstituted tobacco by gas chromatography

A device is described which allows the separation of tobacco from cigarettes at a rate of 2000 cigts/hour whilst the cigarette paper remains intact
