In Situ Carbon Isotope Analysis by Laser Ablation MC-ICP-MS

Analytical Chemistry, 2017
Carbon isotopes have been widely used in tracing a wide variety of geological and environmental processes. The carbon isotope composition of bulk rocks and minerals was conventionally analyzed by isotope ratio mass spectrometry (IRMS), and, more recently, secondary ionization mass spectrometry (SIMS) has been widely used to determine carbon isotope ...

Isotope ratios on transient signals with GC–MC–ICP-MS

International Journal of Mass Spectrometry, 2005
Abstract ICP-MS instruments with multiple ion collectors (MC–ICP-MS) provide highly precise and accurate isotope ratio measurements. These instruments are easily coupled to chromatography, laser ablation or flow injection devices because of the ICP source, and thus attract general analytical interest for measurement of highly precise element isotope ...
