Uranium Detection and Isotope Ratio Determination Using Orbital-MS


EMSL Project ID
49599

Abstract

The proposed work is in support of a funded NA-24 Next Generation Safeguards Initiative (NGSI) Technology Development project. The safeguards community desires that the mass spectrometric capability of elemental detection and isotope ratio analysis, particularly for uranium, be at or near the inspection sites. Among other things, this will require techniques of minimal sample preparation and ionization for MS analysis. One of the techniques we think promising for this application and wish to study is matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-ToF-MS). We propose using the EMSL User Facility’s MALDI-TOF capability to study the MALDI potential for ionization, detection, and isotope ratio analysis for a variety of elements, including uranium, and using a variety of matrices, including various carbon forms and no matrix.
