ABSTRACT:
The method of detecting and identifying a substance in a sample requires the sample to be changed from a first temperature to a second temperature, the sample scanned with an instrument for measuring infrared radiation, the temperature difference between the temperature of the substance at the sample's first and second temperatures determined, and the substance identified based on this temperature difference. The infrared method allows for the objective determination of a substance in a sample without the necessity of the labor and time required in conventional methods and is especially suitable for detecting the presence of "stickies" in recycled paper.
