Stable isotope analysis of oil samples

Bulk analysis of oils and fractions as wel as component specific isotope analysis (CSIA) of oil samples

n-alkane CSIA

n-alkane CSIA

Analysis of carbon and/or hydrogen isotopes on the n-alkanes in an oil or mixture. N-alkanes will be separated from the oil/mixture before the analysis using the method as described in Grice et al, Organic Geochemistry 39 (2008) 284–288. Because of this pre-separation, high precision results can be obtained. The analysis will be done at least in triplicate and will be calibrated regulary against various isotope standards.

C6-C7 range CSIA

In the range propane-toluene the carbon isotopes of ca. 19 components will be analyzed depending on their relative concentrations. Analysis can be done on oil as well as gas samples and will be performed at least in triplicate.

C6-C7 range CSIA

Bulk isotope analysis by EA-IRMS

Besides CSIA where each component is individually analyzed, samples can also be analyzed in bulk by elemental analyzer isotope ratio mass spectrometry (EA-IRMS). Some of the possibillities are:

  • Carbon isotopes of oils and oil fractions
  • Hydrogen isotopes of oils and oil fractions
  • Total carbon or organic carbon isotopes of rock/kerogen samples
  • Carbon/hydrogen/nitrogen isotopes of many other substances, please contact us for the possibillities
