Our ThermoScientific Element XR double-focusing sector field-inductively coupled plasma-mass spectrometer (SF-ICP-MS) is equipped with a Faraday detector and a dynode combined with a secondary electron multiplier (SEM). Hence it allows detection of a wide range of signal intensities (the dynamic range of counts per seconds encompasses 1012 cps). This enables the analyses of ultra-trace element levels simultaneously with major elements. Three different modes of mass resolution allow separation of molecular interferences from signal peaks of interest. Except for H, He, C, N, O, and the noble gases, the Element XR at the Institute of Mineralogy is capable of analyzing every element of the periodic table.
