Mechanisms of Radionuclide-Hyroxycarboxylic Acid Interactions for Decontamination of Metallic Surfaces

Rapid Determination of Uranium Isotopic Abundance from Cotton Swipes: Direct Extraction via a Planar Surface Reader and Coupling to a Microplasma Ionization Source

“…40 In fact, uranium sorption to metal surfaces, such as mass spectrometer ion lenses, is well-known. 49 For each sample, a triplicate analysis was performed at different locations on the swipe. To ensure the background influences were minimized, a blank swipe was sampled in between the anlayses such that a given sequence of a swipe would be as follows: blank, sample position 1, blank, sample position 2, blank, sample position 3, blank.…”

“…The possibility of uranium memory effects might have been expected as previous work utilizing the LS-APGD coupled to the Q-Exactive Focus for direct injections of uranium-containing solutions did suffer from carryover for time frames of minutes . In fact, uranium sorption to metal surfaces, such as mass spectrometer ion lenses, is well-known …”
