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 and a reference temperature 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.
