Summary:
Objective of the study is to highlight differences between GC-IRMS and one of the possible alternative solutions for carbon isotope detection, Cavity Ring-Down Spectroscopy (CRDS), screening both pros and cons of the two approaches in extracting isotopic information from mud gas. Comparison will not only include analytical criteria such as accuracy and precision, but also advantages and drawbacks directly correlated to the specific field of application, e.g. necessity of a large dynamic range, being mud gas sample highly variable in concentration, and possible presence of “contaminants” such as alkenes artificially created by drilling bits or influence from biogenic methane mixed with target analytes.
