The IsoPrime100 is a high performance gas source stable isotope ratio mass spectrometer designed to operate in dual inlet or continuous flow modes of operation. As part of the IsoPrime100 system, Isoprime Ltd. delivers the widest range of sample preparation and presentation modules for the analysis of a diverse range of sample matrices. The modules are designed to handle samples such as solids, liquids or gases and prepare them to be introduced into the ion source of the IRMS as purified gases. Resultant prepared gases such as (H2, CO2, CO, N2, SO2 or N2O) are then ionised and analysed for their isotopic content by the IsoPrime100 IRMS.
