Problems solved by technology

However, this method may also be undesirably subject to high relative errors and high variability for small sample areas and low flow rates.
However, this reference does not describe an apparatus suitable for measuring small band areas of a sample.
However, such a method is undesirably limited by destruction of the sample and the amount of time required to perform the test.

Abstract

An apparatus for measuring a property of a cigarette paper wrapper is provided and includes a sampling device having a first chamber portion capable of being engaged with a corresponding second chamber portion to define a sampling area configured to receive the wrapper such that the wrapper spans the sampling area and separates the chamber portions. A first gas source supplies a carrier gas to the first chamber portion and a second gas source supplies a detectable gas to the second chamber portion. An analyzer device in communication with the first chamber portion receives a resultant gas flow that includes the carrier gas and any of the detectable gas entering the first chamber portion through the wrapper. The analyzer device is capable of determining an amount of the detectable gas in the resultant gas flow so as to thereby determine a property of the cigarette paper wrapper, such as a diffusion coefficient with respect to the detectable gas. An associated method is also provided.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to smoking articles and, more particularly, to an apparatus for measuring a property of a paper material suitable for use as components of such smoking articles. [0003] 2. Description of Related Art [0004] Popular smoking articles, such as cigarettes, have a substantially cylindrical rod shaped structure and include a charge, roll or column of smokable material such as shredded tobacco (e.g., in cut filler form) surrounded by a paper wrapper thereby forming a so-called “tobacco rod.” Normally, a cigarette has a cylindrical filter element aligned in an end-to-end relationship with the tobacco rod. Typically, a filter element comprises plasticized cellulose acetate tow circumscribed by a paper material known as “plug wrap.” Certain cigarettes incorporate a filter element having multiple segments, and one of those segments can comprise activated charcoal particles. Typically, the filter el...
