Spectral interferences using Inorganic Mass Spectrometry

Analysis of Human urine after administration of Gd-based MRI contrast agents

Administration of Gd-based MRI contrast agents causes major spectral interferences during analysis of selenium (Se) and platinum (Pt) in urine.

The finding was reported in a new study led by Amy Steuerwald who carried out an epidemiological study on 619 urine specimens to determine Se and Pt using quadruple-based inductively coupled plasma mass spectrometry (Q-ICP-MS). Both Se and Pt were several orders of magnitude greater than the upper limit of the population reference ranges.
