摘要： An apparatus, method and computer program product for determining a concentration of a high-Z material in a material sample. The method comprises steps of: receiving a material sample and subjecting the material sample to a first sensor device that is substantially ash insensitive for generating a first sensor response signal, and a second sensor device that is sensitive to presence of high-Z material and generating a second sensor response signal. Both the first and second sensor response signals from the first and second sensor devices are processed simultaneously to extract a weight of the high-Z material additive. The weight of the high-Z material additive is determined in a single scan of the material sample.

摘要： A system, method and computer program product is provided that enables measurement and determination of the relative material composition of ash content in a paper product. While materials in ash content, e.g., CaCaO3, Clay, and TiO2, have distinct x-ray absorption spectrum, by varying an X-ray gauge rapidly, measuring the absorption at each energy level and, comparing this to tables of fundamental physical parameters, the relative fractions of materials in ash content, e.g., CaCaO3, Clay, and TiO2, can be extracted. The relative weights of other constituent materials found in web or sheet paper products are additionally determinable.
