Stable isotope mass spectrometry

Head: István Fórizs

The 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. In 2005 a new continuous-flow Finnigan delta plus XP mass spectrometer was purchased and installed. It can analyse the same isotope compositions, but the required sample amount is very low down to 1 micromole.

Electron microprobe

Head: Gábor Dobosi 

The 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 quantitatively.

X-ray diffraction (XRD) and X-ray fluorescence (XRF)

 
Head: Mária Tóth 

The X-ray 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.

The XRF 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.

Organic geochemistry and analytical chemistry

Head: Csanád Sajgó 

Main 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.
Instrument: A Fisons 8360 gas chromatograph.
Main activity of the analytical chemical laboratory is qualitative and quantitative analysis of rocks and minerals. Samples are digested and dissoluted by adequate decomposition techniques. Facilities: Perkin-Elmer 5000 Atomic Absorption Spectrometer, Pye Unicam SP 1800 Spectrophotometer.
