| Definition | An Isotope-Ratio Mass Spectrometer (IRMS) which operates in dual inlet flow mode for the measurement of the isotope ratios d13C/12C, d18O/16O and d34S/32S. It is used to determine the d13C/12C of carbon in different materials (organic matter, dissolved carbon in water), d13C/12C and d18O/16O in carbonates, d18O/16O and d34S/32S in sulphates and d34S/32S in sulphides. The natural sample is processed first (e.g. combustion, acid attack, or purification) in order to obtain a directly analysable gas. The prepared gases (CO2 or SO2) are then ionised and analysed for their isotopic content by the IRMS. This model is no longer in production. | ||
