AI-generated Abstract

This research presents an innovative approach for δ13C analysis of rock samples using Flash Combustion–Cavity Ring Down Laser Spectroscopy (CRDS). The study demonstrates that optical isotope determination can serve as a viable alternative to traditional ionization mass-spectrometry, offering higher precision, lower operational complexity, and cost-effectiveness. Direct comparisons of δ13C measurements from both CRDS and conventional methods exhibit minimal discrepancies, supporting the reliability and effectiveness of the laser-based approach in geochemical applications.
