Geochemical studies

Geochemistry is the science about the chemical composition of the Earth and planets (cosmochemistry), the laws of elements and isotopes distribution and movement in various geological environments, the processes of formation of rocks, soils and natural water..Modern geochemistry is a combination of disciplines, including geochemistry, biogeochemistry, regional geochemistry, geochemical methods of prospecting of mineral deposits.

Actual basis of geochemistry are quantitative data on the content and distribution of chemical elements and their isotopes in different sites: minerals, ores, rocks, water and gas, living organisms, structural zones of the earth's crust, the crust, mantle and the Earth as a whole, in various space objects, as well as the forms of location and state of the elements in the natural substance. These data obtaining is based on the geological characteristics of the object, the modern physical and physical-chemical methods of elements content and state determination in the minerals, oil, gas and living matter.

X-ray fluorescence method is one of the most important modern methods due to its simplicity, precision and simple sample preparation.

XRFA provides direct elements determination from Na to U (in particular cases from Be to U) in powder, solid or liquid samples. X-ray fluorescence spectrometers are able to determine very low concentrations from mg/kg, as well as high concentrations up to 100% without sample dilution. That is why XRFA is an universal method of analysis providing  simplicity, precision with simple sample preparation and almost no consumables.

X-ray fluorescence analysis properties are very useful in geochemical research. There are many sample preparation methods developed including dissolving the samples; preliminary concentrating methods provide low limit of determination of first mg/kg.

This allows to solve a lot of problems in geochemical studies with a single method.

SPECTROSCAN МАКС-GVM

"SPECTROSCAN MAKC-GVM" WDXRF spectrometer determines elements from Na (Sodium) to U (Uranium) in solids, liquids or powders, in solutions and thin films, deposits on filters.
