X-ray fluorescent analysis

Oral

A technique combining SR XRF, XRF mapping, μ-XRF, and μ-XAFS for search for microparticles in different matrices and determination of particle size, as well as analysis of their composition and structure, has been developed at Budker Institute of Nuclear Physics. The technique is based on comprehensive examination of sample with gradually increasing the spatial resolution and constricting the...

61. Features of using of the hard X-rays ( 60 – 120 keV ) of synchrotron radiation for determination the trace concentrations of rare-earth and heavy elements by the SRXFA method

X-ray fluorescent analysis

Oral

The 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 excitation energy for the determination of rare-earth elements (La-Lu) and heavy platinoids (Os,Ir,Pt) and also Au was 60 - 120...

Oral

For river ecosystems, one of the site of chemical elements accumulation is benthic assemblages. In our research 20 benthic samples were collected from small rivers and streams from industrial and nature areas of Novosibirsk region. Benthic invertebrates were fixed at 75% ethanol and identified up to the family taxonomical level at the laboratory. After identification samples were dried up to...
