Gasbench ii
WebThe Gasbench II is a headspace gas analyzer. It is primarily used to measure the carbon and oxygen isotope composition of carbon dioxide (CO 2) gas liberated from carbonates … The GasBench Plus System provides high quality analytical results under continuous flow IRMS operation. The sample is carried by helium gas, enabling separation using gas chromatography (GC) and facilitating fractionation-free viscous flow sample transport.
