摘要： The present invention is a method and apparatus for calculating the amount and composition of inorganic material in a sheet material. The apparatus of the present invention is capable of calculating the composition of all the additives at once without requiring multiple cycles. The apparatus uses a combination of two techniques, namely an X-ray fluorescence analysis and a preferential X-ray absorption analysis. X-ray fluorescence is measured by a thermoelectrically cooled solid state detector. The apparatus can measure more than three additives. Measurement of argon in the air is used for compensation of electronic drift. An empirical correction is used to compensate for mutual interaction between X-ray fluorescence radiation and clay or talc. The measurement is compensated for dust accumulation by means of fluorescing the dust.
