Laboratory for Organic Geochemistry And Analytical Chemistry

Since ~1970 organic geochemical studies and analyses had been done at LGR.
The separated organic geochemical laboratory has existed since 1979. 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.
Instruments at the organic geochemistry laboratory:
A Fisons 8360 gas chromatograph (detectors: FID, FPD and ECD; injectors: split/splitless, on-column and multiinjector =MFA815 and Chromcard advanced version; covered by: OTKA C0108), and coupled Quantum MSSV-1 Thermal Analysis system (micro-scale sealed vessel for closed system pyrolysis and on-line injection); Cryo 820 unit for subambient work from -50°C (CO2).
A Pye-Unicam SP-1100 infrared spectrophotometer, made in 1975.

 

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. Major and minor components as well as trace constituents of the dissoluted samples are analysed by a combination of atomic absorption, spectrophotometric and classical analytical methods. Facilities: Perkin-Elmer 5000 Atomic Absorption Spectrometer, Pye Unicam SP 1800 Spectrophotometer.
