MAT253

The MAT 253 is the Gold Standard for isotope ratio MS.  It delivers the highest sensitivity and precision for the determination of isotope ratios. It is unique in its ability to achieve precision measurements from the smallest amounts of sample and delivers the highest precision for the determination of H/D, 13C/12C, 15N/14N, 18O/16O, 34S/32S (from SO2 and SF6), 28Si/29Si as well as Ar, Kr and Xe isotope ratios. This instrument provides a flexible and open platform for the connection of inlet systems and preparation devices.

The analyzer geometry with stigmatic focusing, and the largest dispersion by far of any gas IRMS (46 mm), is the foundation of the MAT 253’s analytical performance and ruggedness. It ensures perfect peak shapes, unrivaled mass resolution, and a mass range which covers all stable isotope applications. All gas species except H2 are measured using the full deflection radius.

H2 is measured on a smaller radius with an effective dispersion of 180 mm.  The magnetic sector field is generated by an electromagnet.  The field strength is controlled by a high precision current regulator which is under full data system control.
