A METHOD OF DETERMINING THE BACKGROUND CORRECTED COUNTS OF RADIATION QUANTA IN AN X-RAY ENERGY SPECTRUM

摘要

The invention relates to a method of determining the background-corrected counts of radiation quanta of an X-ray energy spectrum relating to a sample of interest. To this end, two or more different measurement windows are defined in the spectrum. In these windows the counts of radiation quanta are measured and a pair consisting of a first and a second measurement window is selected. A background signal for the first measurement window is calculated on the basis of the counts of radiation quanta in the second measurement window while using a relation defined between said pair of measurement windows. Said background signal is subtracted from the counts of radiation quanta in the first measurement window, thus yielding the background-corrected counts of radiation quanta in the first measurement window. A spectrometer with means for carrying out the steps of the method and a computer program for carrying out the steps of the method are also provided.
