| Definition | The Thermo Scientific MAT 253 stable isotope ratio mass spectrometer is designed to determine isotopic ratios of D/H, 13C/12C, 15N/14N, 34S/32S, 28Si/29Si, Ar, Kr, and Xe. It can be used in dual inlet mode or continuous flow mode. The instrument includes amplifiers up to 50 V, hydrogen continuous flow capability, up to eight simultaneous acquisition channels, and the integration of Isodat software. Its analytical performance and ruggedness are due to the geometry with stigmatic focus and large dispersion. The magnetic sector field is generated by an electromagnet. Collectors are located at the focal plane of the full deflection radius, and they use individually shielded Faraday cups. The MAT 253 has a mass range of 1-150 Dalton at 10 kV, a sensitivity of 600 molecules CO2 per mass 44 ion in the dual inlet mode, and 900 molecules/ion in the continuous flow mode. For this instrument, the ambient temperature must be 18 - 28 deg C, with a relative humidity of 20 - 70 %. It requires power 230 V. and compressed air 350 - 500 Kpa (50 - 75 psi). | ||
