Thermo Scientific Kiel IV Carbonate Device is highly sensitive, ultra-precise isotopic measurements in an automated, high-throughput workflow with the. This device, when coupled to IRMS, enables analysis of carbonate samples during paleoclimatic reconstructions involving biogenic carbonates such as foraminifera, bivalves, brachiopods, otoliths, and corals. Other applicable fields of study include analysis of growth zones of individual organisms or microfossils from drill cores.
