Keywords:

  • mass spectrometry versus isotope ratio mass spectrometry;
  • molecular mass spectrometry (MS), using single detector - cannot continuously detect particular isotopologue ion pair;
  • high-precision stable isotope analysis - minute changes in 13C isotopic abundance detected;
  • multicollector isotope ratio mass spectrometer - instrument of choice to determine origin of organic compound;
  • selected ion monitoring (SIM) mode - 50% of detectable ions lost to detection
