摘要： Humic acid-dyed paper suitable for use as wrappers for smoking articles is post treated with magnesium sulfate to fix or render the humic acid insoluble. Paper treated in this manner provides a product of acceptable brown color. Smoking articles wrapped in the treated paper evolve a reduced amount of carbon monoxide on smoking under normal conditions in comparison to currently available brown papers stained with humic acid.

摘要： Methods and apparatus for continuously and instantaneously measuring sidestream smoke are provided. A hood assembly is provided to fit over the ports of a conventional smoking machine. Sidestream smoke produced by test cigarettes is continuously drawn through the hood by an exhaust system. A laser beam is passed through the smoke one or more times before the beam is sensed by a photodiode detector. An electrical signal from the detector, representing the light transmission, is received by a strip recorder or computer system. The transmission measurements are used to calculate the extinction coefficient of the smoke for comparison purposes.
