Material base of the laboratory

1. JNM-ECA 400. Nuclear Magnetic Resonance Spectrometer

The spectrometer is a fully automated device designed for physico-chemical research for scientific, educational and commercial purposes.
NMR spectrometer Jeol JNM-ECA 400 is used in chemistry, medicine, ecology, energy and other industries for the most qualitative and accurate analysis of the composition of liquid media in order to determine such important indicators as the structural formula, electronic and spatial structure of the substance, the degree of its purification and isotopic composition, fragmentary, structurally-group, and also component compositions, hierarchy of technological transformations. The number and position of the lines in the NMR spectra unambiguously characterize all fractions of crude oil, synthetic rubbers, quality control of new polymeric materials, shales, coals, drugs, preparations, products of the chemical and pharmaceutical industries. In addition, you can assess the safety of grain, measure the moisture and oil content of seeds, record the content of gluten in the grain.
