The application hard X-rays of synchrotron radiation for determination of the minimum detection limits of heavy platinoids (Os,Ir,Pt) and Au by the XRFA-SR method
The experiment on analysis of the elemental composition of samples by their X-ray fluorescence spectra were performed at the synchrotron radiation station using radiation from the 9-pole wiggler on VEPP-4M at the Siberian Center for Synchrotron and Terahertz Radiation (SSTRC). The samples Russian and International standarts were used (G-3, KN-1, KM-1, VP-2, GMD-4, GMD-5, COG-13-3). The results on the minimum detection limits (MDLs) of heavy platinoids (Os,Ir,Pt) and Au based on the lines of the K series of the characteristic radiation excited by photons with energies of 100 KeV were obtained.
The work was done using the infrastructure of the Shared-Use Center "Siberian Synchrotron and Terahertz Radiation Center (SSTRC)" based on VEPP-4M of BINP SB RAS (Novosibirsk, Russian Federation). This work was funded by the RFBR and Government of the Novosibirsk Region within the framework of the research project 17-45-540618.
