"A laboratory instrument which prepares water samples for isotopic analysis using a H2O-CO2 equilibration system. The instrument requires 3 ml of water for one measurement to be made. The IsoPrep 18 is usually coupled with an Isotope-Ratio Mass Spectrometer (IRMS) where the prepared gases are then ionised and analysed for their isotopic content."@en . . . . . .
