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 ; skos:inScheme ; skos:notation "SDN:L22::TOOL0567" ; skos:note "accepted"@en ; skos:prefLabel "VG IsoPrep 18 water equilibration device"@en ; skos:related . skos:narrower . skos:related . skos:related . skos:narrower .
