摘要： A method (100) of measuring chemical species in a sample by x-ray fluorescence comprising the steps of: - arranging (110) a sample to be analysed including one or more chemical species to be identified and measured, - exposing (120) the sample to x-radiation, - measuring a spectrum (130) associated with the chemical species, - recognising (140) the chemical species by identifying the energy value of one or more peaks of the spectrum, - calculating the mass (150) of each of the chemical species by analysing said spectrum, on the basis of the number of counts associated with each of the peaks (K, L) of the measured spectrum, the mass of each of said chemical species being calculated on the basis of the number of counts associated with each of the peaks (K, L), - a preliminary calibration step (101) wherein a linear relationship between the number of counts associated with each peak and the mass of the corresponding chemical species associated with said peak is identified by deposition of a plurality of calibration solutions on respective rough, impermeable surfaces (55) of respective calibration supports (50) that are identical to each other, each of said calibration solutions comprising a predefined amount of a chemical species.
