A New Approach to Extending the Dynamic Range in Inductively Coupled Plasma-Mass Spectrometry.

: By the use of a new simultaneous dual stage discrete detector for inductively coupled plasma-mass spectrometry (ICP-MS), a linear dynamic range of 8 orders of magnitude was achieved in a single spectral scan. The design of the detection system and its evaluation are described. The acquisition of the full spectrum of a human urine sample in a single scan is shown.
