Abstract

RATIONALE: We have used a high-precision, high-efficiency method for the measurement of the

METHODS: The technique described here involves Isotope Ratio Mass Spectrometry (IRMS) on-line in continuous flow mode with an Elemental Analyser (EA) using "purge and trap" technology rather than separation by conventional packed column gas chromatography (GC). The system is equipped with a special high-temperature furnace reaching 1500°C, with a longer hot zone and improved temperature stability. Emphasis is put on the efficiency of the system to reliably pyrolyse refractory minerals difficult to analyse with other conventional systems.

RESULTS: While conventional systems usually fail to generate hydrogen suitable for isotopic analyses, with the technique presented here we were able to measure

CONCLUSIONS: The possibility of using such a system to reliably measure
