Laboratories and research
Stable isotope mass
Head: Attila Demény
laboratory was established in 1990. Until 2005 the stable isotope
laboratory was equipped with a Finnigan MAT delta S isotope ratio mass
spectrometer that has a collector system for 13C/12C,
18O/16O, 15N/14N and
34S/32S ratio determinations in CO2, N2
and SO2 gases, and a collector system for D/H ratio
determination in H2 gas. Now the lab also contains to other mass spectrometers. In 2005 a
Finnigan delta plus XP mass spectrometer equipped with a GASBENCH II unit was installed.
Although water samples can be analysed using CO2-H2O equilibration, the mass spec is currently used only for
carbonate samples. In 2014 a Thermo Finnigan delta V mass spec was purchased and a TC/EA and and elemental analyzer were attached
in order to measure H-C-N-O isotopes in organic matter and hydrous minerals. H-O isotope compositions of water samples are measured
using two laser spectroscopes (Los Gatos Instruments), one of them dedicated to fluid inclusion research.
Laboratory for mineral and rock analyses
Head: Péter Sipos
The major profile of the laboratory is the analysis of geological materials for their chemical and phase composition; however, significant experiences are possessed on the analysis of (industrial) ceramics, metals, glasses, and materials of the cultural heritage. Its special areas of analysis are the clay mineral identification and structure analyses, the archeometric analysis, as well as the integrated phase and chemical micro-analysis.
The laboratory consists of three parts: an X-Ray analytical, a micro-analytical and an inorganic chemical unit. An X-Ray micro-diffractometer, two X-Ray diffractometers, a laboratory and a handheld X-Ray fluorescent spectrometer, an electron microprobe, an atomic absorption spectrophotometer and an automatic titrator are operated in the laboratory. Basic and special sample preparation tools are also available there.
laboratory is equipeed with a Philips PW 1410 type
wavelength-dispersive X-ray fluorescence spectrometer controlled by
Philips X31 version 2.13 software is used at the
Institute for Geochemical Research.
Sample preparation laboratory for
in-situ produced cosmogenic nuclides
Head: Zsófia Ruszkiczay-Rüdiger
The setup of a sample preparation laboratory for in-situ produced cosmogenic nuclides in our Institute begun in 2013.
From 2014 to 2016 the laboratory has been prepared for processing quartz-containing sediment and rock samples for the determination of their in-situ produced cosmogenic 10Be and 26Al concentrations.
Main research topics: exposure age and denudation rate determination of fluvial terraces using 10Be depth profiles,
burial age determination using the 26Al/10Be nuclide-pair and 10Be exposure age determination of glacial landforms.
