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.
Head: Péter Sipos
electron microprobe laboratory is operating since 1969. At present we
use a JEOL JCXA-733 instrument (installed in 1980), equipped with 3
wavelength dispersive spectrometers and an Oxford Instruments INCA
Energy 200 energy dispersive spectrometer (installed in 2002). At
present, we can analyse virtually all elements from F to U
X-ray diffraction (XRD)
and X-ray fluorescence (XRF)
Head: Péter Sipos
diffraction (XRD) laboratory is equipped with a Philips PW 1730 X-ray
diffractometer controlled by PC-APD software. Graphite monochromator
and Cu tube are used. Facilities for a range of sample preparation
methods are available.
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.
Head: József Fekete
activities at the laboratory were as follows: source rock and crude
oil studies, including analyses of aromatic and non-aromatic
hydrocarbons, kerogen studies, including kerogen factory, thermal
degradation and simulation experiments, analyses of pyrolysis yields,
pyrolysis gas chromatography, MSV type analyses.
Instruments: Fisons gas chromatographs and DANI GC-TOF-MS.
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.
