Espectrometro de massa MAT253 acoplado a Kiel IV

The Finnigan MAT 253 stable isotope ratio mass spectrometer system delivers the highest precision for the determination of D/H, 13C/12C, 15N/14N, 18O/16O, 34S/32S (from SO2 and SF6), 28Si/29Si as well as Ar, Kr and Xe isotope ratios. The KIEL IV Carbonate Device connects to Thermo Scientific MAT 253. The KIEL IV Carbonate Device consists of a thermostated reaction region, a trapping and gas cleaning system and a microvolume inlet system. The KIEL IV Carbonate Device uses the principle of the individual acid bath for conversion of carbonates to CO2. Storage, transfer and chemical reaction of phosphoric acid at elevated temperatures are operated under full temperature control. Septum-free vials are used for the phosphorolysis of the carbonates. All CO2 released is transferred and processed in an all-metal sealed cryogenic trapping system.
