Laboratory of Environmental Geochemical Analysis

Head of the laboratory: Dr. T. Matys Grygar 

Analytical Laboratory was a small service workplace since 1990s, which performed characterisation and conventional chemical analysis of products from other laboratories of the Institute. Later we have developed a solid-state voltammetric analysis of Fe and Mn oxides and succesfully used it in numerous materials and geochemical studies, mainly in collaboration with Czech universities. Today the Laboratory is focused on development of novel approaches to analysis of solids with particular orientation on chemical materials (mainly in collaboration with V. Štengl, Deparment of Materials Chemistry) and unconsolidated na sediments (more details in the section of Research). Major parts of the Laboratory activities are now own research and training of university students.

Laboratory disposes of an ED XRF spectrometer, a Raman microscope and an AAS-AES with flame atomization.
