Used equipment See all
X-ray Diffractometer DRON-7
Designed for polycrystalline research. Analysis of the phase (mineral) composition of polycrystalline materials. Research of their structural characteristics and degree of purity; an impact of various technological treatments on the degree of purity, nano (micro)-structure and properties of these materials (metals, catalysts, semiconductors, substances, pharmaceuticals, etc.); research of polymorphism.
Fourier Infrared Spectrometer Nicolet 6700
It allows identifying components of substances of unknown composition, analysis of objects, petroleum products, oils, ceramics, polymers, coatings, medicines, molecular structure. Multicomponent analysis is conducted for organic and inorganic compounds (solid, liquid and gas ones) in the average spectral range of 4,000-400 cm-1, as well as in the far region up to 200-50 cm-1.
Atomic Absorption Spectrometer Shimadzu АА-7000
Allows conducting the analysis of liquid and liquid-transferred samples. Determination of the content of elements from sodium to uranium in the range of 0.0001-100% allows analyzing samples of small volume (from 50 μl) with flame and electrothermal atomizers. Determination of the content of heavy metals in fodder, water, soil, medicinal products, biological fluids, medical products; the analysis of air, food, agricultural products and alcohol-containing products, petroleum and oil products, lubricants, the composition of the obtained new substances, catalysts, sorbents, reaction products, fertilizers, glass, ceramics and steel.
Energy-Dispersive X-ray Fluorescence Spectrometer Clever C-31
Allows conducting non-destructive express analysis of the composition with minimal sample preparation, analyzing solid and liquid samples, including filtration residues. Determination of the content of elements from sodium to uranium in the range of 0.0001-100%
Gas Chromatograph Crystal-5000
Analysis and separation of mixtures of organic substances. It is possible to analyze from simple gases to the determination of complexes of substances in complex matrices, as well as to determine the sorption ability and conduct online analysis for continuous processes.
Chromatograph Mass Spectrometer Thermo Focus DSQ II
Designed to establish the qualitative and quantitative composition of complex mixtures of organic compounds. The availability of the mass-spectral database NIST 14 and the software package for automatic deconvolution of AMDIS makes it possible to perform the unique identification of compounds at trace levels.
Elementary (CHNS) Analyzer Euro Vector EA-3000
Euro Vector EA-3000 is an ideal solution for the elemental analysis of products of fine chemical synthesis. A small amount of operational sample weight, about 1 mg, allows researchers not to spend an excessive amount of valuable compounds for combustion. The accuracy of the measurements is as follows (with 10 parallel determinations, sample weight of 1 mg): 0.3% <(C), 0.1% < (H), 0.1% <(N), 0.2% <(S).
Liquid Chromatograph Mass Spectrometer Shimadzu LCMS-8040
A liquid chromatograph mass spectrometer with a triple quadrupole mass analyzer allows conducting HPLC/MS and HPLC/MS/MS, qualitative and quantitative analysis of mixtures of natural and synthetic organic compounds, pharmaceutical products and substances, clinical and biological samples, including bioequivalence tests.
Multi-Function Tablet Analyzer Tecan Infinitе M1000 Pro
Tecan Infinite M1000 Pro allows measuring the optical density with high accuracy in the range from 230 to 1,000 nm in 1 nm step, including luminescence, and studying the biological activity by spectrometric data. Test methods improved in our center allow searching for new inhibitors of cholinesterases with the use of Tecan Infinité M1000 Pro.
