Chemical elements in a sample were excited by radioactive isotope sources (Fe55, H3-Zr and Am241) or X-ray tube (gold target and silver target). In the process, some characteristic X-rays were emitted unique to each element. Energy and the net peak area of characteristic X-ray were measured by Si detector and Amptek DppMCA spectra analysis software. From there, the composition and concentration of interested elements could be determined.
