Project target

1. Development of a radically new analytical technology offered by a Leading scientist – method of fractionalization of trace elements and  nano/sub micro/micro particles of technological and natural samples  in crossflow force field in a rotating helically-formed column of an original construction for further elemental and speciation analysis.

2. Research and development of new organic sorbents for separation and pre-concentration of non-reactive and rare earth disperse elements – precursors of functional materials.

3. Development of complex chemical-atomic-emission, chemical-atomic-absorption and chemical-mass-spectral methods of inorganic analysis with enhanced metrological characteristics.

4. Development of procedures for elemental and speciation analysis of finely divided particles of technological samples (including powdered finely divided functional material) and environment objects (soil, dust, ash)  using the offered methods of separation and pre-concentration.

Project objectives

The tasks of the project are: development in NUST MISiS of highly efficient advanced methods of separation of trace elements and  nano/microparticles using sorption process and flow-type fractionalization in crossflow force field; development of complex methods of chemical diagnostics of functional disperse materials and environment objects;  efficient use of instrumental basis of the University. 

Uniqueness project

The team has developed radically new approaches and methods to solve the above tasks, including unified methodological approach to materials and substances analysis, which covers all stages of the process, such as sample preparation, separation, pre-concentration, metrological support, results processing, use of mutually complimentary methods; development of new advanced method of separation of micro elements, micro and nano particles using rotating helically-formed column; development of new specific organic sorbents for various materials based on non-ferrous, precious and rare materials; and finally combination of the developed methods of separation with such modern analysis methods and mass-spectrometry, atomic spectrometry, X-ray analysis and as a result – development of complex analysis methods with enhanced metrological characteristics. Chemical analysis is an integral part of any research, any technology of creating the variety of inorganic materials – ferrous, nonferrous, rare, precious metals, alloys and various composites on their basis. Practically all analysis methods are based on emerging analytical signal as a specific reaction of substance or material to exposure to such factors as high temperature, various types of radiation – light, X-rays, current of elementary particles, chemical reactions, etc. with further measurement of analytical signal. This principal is basic for hundreds of analytical instruments – spectral, mass-spectral, nuclear-, physical, X-ray, which cover a wide range of problems solving – elemental, isotopic and molecular analysis of substances and materials. In spite of great number of modern devices, high level of computerization, potential analytical features can be realized only in combination with methods of separation and pre-concentration. A crucial peculiarity of analytical measurements is their strong dependence on chemical composition of the sample, mechanical impurities. Thus to separate pure analytical signal we use all advanced achievements of analytical instrumentation – resolution enhancement, different types of mathematical processing, etc. A new scientific discipline appeared – chemometrics. But the most radical way to purify analytical signal from external impact is separation and pre-concentration of components and impurities in the sample.
