Analyzed objects

Analyzed elements











Any objects in a power and liquid form

Al to Pu


Analyzer of minute quantities of substance (TXRF-8030ñ). Energy dispersion X-ray fluorescent method with complete and external reflection (coming in 2003)

Excitation sources: Mo-, Ag-, W-pipes; collimation systems of exciting and recording radiation. DetectorSi(Li) with  RMn=150eV.

1) In solid state, same as in EDRXF.

2) In liquid state, with clear, desalted matrix from K-solution (m ≥k.μkg). Detection limit along K-lines up to 10-8%. Simultaneous analysis of all elements


Any objects in a power and liquid form

K to Br – along Ê-lines, Âr to W –along L-lines

Energy dispersion X-ray fluorescent method with radionuclide excitation source (EDRXF)

Excitation source–Pu238 isotope. Detector – Si (Li) with RMn=190 eV.

Simplified sample preparation, sample analysis, m ≥10μg. Detection limit (Lim) (along Ê-lines), up to 10-3÷-4%; along L-lines, up to 10-2÷-3%. %. Simultaneous analysis of all elements


Any objects, converted into solution

Alkali, alkaline-earth, noble and transition metals, rare earths, mercury, etc.

Atomic absorptive analysis

ÀÀ-780 and GGX-6A Atomic absorptive spectrophotometers, AAS vario 6 graphite dish, mercury analyzer “Yulia”-2m

Minimal volumes of analyzed solutions (of the order of 5-50μl). Absolute sensitivity of determinations varies from (1-2)·10-12g for cadmium and zinc, up to (2-3)·10-10 g for nickel, titanium and vanadium. This allows determination of element concentrations of the order of 10-9 g/ml in a 20μl-sample solution. Duration of one cycle 1-2 min.



Rocks, minerals, soils, and other objects

The whole range of elements

Semiquantitative spectral analysis

PGS-2 spectrometer.



Atomic structures of monocrysts of nonorganic and organic bioorganic origin

X-ray structure analysis

"Bruker SMART 1000 CCD" X-ray diffractometer. The diffractometer is equipped with a low-temperature attachment allowing measurements in a temperature range of 300 to 77K.

High sensitivity of detector and high precision of setup angles of goniometer (±0.0005°) make it possible to substantially minimize X-ray experiment time conditioning qualitative results. The software allows computerization of information processing


Powders, films, solutions, gases

IR-, Raman-spectroscopy (combinational scattering)

EQUINOX 55S infrared Fourier spectrometer (“BRUKER”). The spectrometer uses a He-Ne-laser with a wavelength of 633km nm (red), 1mW.

The OPUS/IR program package controls the spectrometer, signal registration and spectra processing. Supplementary ports for the beam allow a wide range of different detachable devices, including an infrared microscope, a Fourier-Raman module FRA 106/S for ÊD spectra
